Maybe using Google Maps or Google Earth you can zoom in and determine the road conditions??

Did you notice in the lower left of the screen there is a "Page 1 of N" display? Look at the other pages.

Off topic:
No, I did not. But now it works. I have to admit: The device itself is beautifully engineered, but the online services are extremely poor. I'm a bit worried that all my friends and relatives will never grasp how the data points are displayed once I give them the link. I mean: If I can't figure it out - how should they?

Great report and great pics. But why does your SPOT GPS only show data for a very short distance? I will also be carrying a SPOT device on my tour which starts in roughly 35 days and I'm very happy to see how well your device works.

Hi,

Have you been puzzled what crops you see along the way?

With these map collections:

http://www.nass.usda.gov/Charts_and_Maps/Crops_County/index.asp#as

you will know what crops you are passing through when riding in the US.

General Discussion / Sierra Cascades: Which clothes?
« on: April 08, 2012, 03:41:18 pm »
Hi,

As part of my cross country tour I will be doing the Sierra Cascades from North to South. Leaving the Transam in Sisters, OR, I will pick up the Sierra Cascades in the 1st week of July. I know it will be horrendously hot in the southern part. Having crossed the Rockies (where cold weather clothing is needed), I need to know around what location it would be advisable to send home some warm clothes? What about rain gear - what is the chance of rain?

Summer 2000 I did the Pacific Coast: On this trip however, it was often cold and rainy and warm clothes were mandatory.

Off topic:

Spokes have tensile strength of approx 1100 MPa.
Typical spoke diameter is 2 mm.
Lets assume you have 2 wheels both with 36 spokes. On each wheel 18 spokes act as "braking spokes" due to the spoke pattern. In total you have 36 "braking spokes".

Main formula: p=F/A

where p=pressure=tensile strength
F=Force
A=Cross sectional area

Lets calculate the cross sectional area

A=3,14/4*2^2=3,14 mm^2

F=p*A
F=1100*3,14=3454 N

With a total of 36 braking spokes you have 3454*36=124344 N

which equals 12,6 tonnes.

Now, unless you are able to stop your bike literally within a fraction of a second (=enormous decelleration) I hereby claim that you will never reach the 12,6 tonnes limit. Now, one can extend the calculus with all different kinds of variables, but this was only to show how strong spokes actually are.

As a comparison:

Construction steel tensile strength: 370 MPa
And the beforementioned stainless steel spoke: 1100 MPa

... and even higher for thinner spokes.

Thus, spoke material is 3 times stronger than construction steel.

However, if your spokes have experienced extensive fatigue due to bad/wrong wheel building, a large strain like a downhill brake might just be what is required for a snap. But thats a different story and disc brakes cannot be accused for that matter.

Now, this doesn't mean I run disc brakes myself. I have used disc brakes and they are fun in dry sunny weather in town. I only run hydraulic rim brakes (=Magura). My Maguras have not required any service or a drop of oil for the last 13 years.

General Discussion / Re: No restrooms?

"Camping in city park, no restrooms."

How does that work...no restrooms while camping in a city park?

I guess it works just like it says! The town/city has offered their park to cyclists, however there are no services except a lawn and maybe a shelter. In turn, such a city park is probably for free and this is why I love these parks. Not far away you will probably find a gas station or a McDonalds with rest rooms.

This is how I interpret it.

Routes / I have an old Southern Tier map ...
« on: March 19, 2012, 02:53:27 am »
Summer 2000 I did the Northern Tier + Pacific Coast + 1st Section of Southern Tier.
Summer 2012 I will do the Transamerica Trail + Sierra Cascades + 1st Section of Southern Tier.

Reason for 1st section of Southern Tier is due to my departure airport in Pheonix, AZ.

3 months ago I ordered all the maps and had them shipped to Europe. Except for the 1st section Southern Tier: I had this map already of course.

Then a few days ago I realize the map is so old that no addendums exist online anymore.

The map is called  #BC-1710 99D

which indicates a print from 1999 I suppose.

Further researching I see that there is a heavy change of route on the first part leaving San Diego:

Whereas the new map closely follows I-8, the old map stays close to the border (HWY 94). Both routes rejoin in Boulevard, CA.

Questions:

1. Is it possible to get an addendum for such an old map?
2. What is the reason for changing the route? I remember the HWY 94 as being very quite and peaceful.

I don't think that's stupid at all. You chances of getting robbed on the TransAm are probably less than one in a thousand,

Somewhat off topic:
My point exactly. Friends/family still don't believe me when I tell them it is more safe to ride across USA (incl probable bear encounters in the Rockies) than having a Friday night out in a European city/town where you have a large chance of getting robbed, stabbed, shot at or beat up by total strangers. People do stupid stupid things when intoxicated by drugs but most importantly alcohol.

But hey, on my Northern Tier trip somewhere in the heartland I was sitting on a porch in front of a tiny grocery store relaxing and eating. A lady came by and gave me 3 dollars so I could buy myself an ice cream  :)

I know that some of you will call this upright stupid ...

On my last trip I had 1000 dollars in hard cash in my wallet. Just a bunch of 20 dollar bills. I will also be doing the TA this summer and again I will start out with 1000 dollars. That should last for 50 days (= the entire trip) excl unexpected mechanical failures. Although I will carry 2 credit cards (emergency) I don't like using them at all because I "loose the grip" of where the money is going. But this behavior is probably reflecting the use of credit/debit cards in my everyday life: I probably use those cards 2-3 times a month. I need to physically see where the money is going. It is as simple and basic as it gets.

And remember the saying:

Money talks
Cash screams

Last year I asked the same question (even with a poll):

Routes / How quickly are addendums updated?
« on: March 17, 2012, 02:33:14 am »
Hi,

This is how I use the addendums:

With a ball pen I write all the important information right on the map. Motels, hostels, B&B are not of interest to me so it boils down to route changes, campground changes and closures/operings of grocery stores/gas stations. That way I don't have to fiddle with 1 extra sheet of white paper pr map when touring. I always did it like that, and I love it. This swapping of information to the maps takes me approx 1 day and is worth every minute spent.

I will be doing the Transamerica starting June 2nd in Washington DC. This is a late start as a realize that many cyclists start in May, maybe even April. Those cyclists will be just ahead of me and able to report on any changes to Missoula.

At the moment I see some addendums from February 2012 already which is good. However, how is the procedure for updating the addendums? If a cyclist reports a change on route, will it just be added instantly without any ACA research?

Just prior to departure things get very hectic for me and I will not have time to print all the information onto the maps the night before departure. So when would be a good time to download the addendums? If the addendums are truly updated instantly I have to pick the latest time possible. If there is a 1 month "processing" time I can relax and have it done a quiet weekend in May.

Thanks for your reply. The link was very informative. I did the Northern Tier in 2000 and very clearly remember ND 1804. A place where you really experience the bad lands.
