Michael -
I don't know about y'all, but I am an ocean-to-ocean person when I ride cross-country.
Ocean-to-ocean is preferrable, but not required for us. If there is a better route that does not include an ocean-to-ocean start/finish, we'd do that, but generally we'd like to do ocean-to-ocean.
Which leaves a couple of options - cycling in January in Montana -
or choosing more out-of-the-way places where you are more likely to find lodging.
January in Montana for us Southern Californians is not an option. We, well really I, start to get pretty whiny when the thermometer drops below 60F.
More out of the way lodging options is not only a better option, it's our preference anyhow. We don't need or even really want to go through Yellowstone. We've been there several other times and love it, but neither the lodging nor the traffic are very appealing to us when we're biking there.
Do you have your passports?
Do you want 100% US of A or would you opt for some Ontario between Michigan and New York state?
Summer touring is just so much nicer in the Northern Tier - plus more & better Mom & Pop motels.
(You have heard about the aircraft carrier they built for the mosquitoes and black flies in Minnesota?)
We have passports and would love to ride in part in Canada. Our trip this past summer (BC - Los Angeles) included a brief (a mere 20-30 minutes) stint in Canada and we would love to see more of the country by bike since we've only seen it by car previously.
If there's a good route that avoids crowded National Parks, like spending some time in Canada, we'd love to get a look at those routes. Currently, the route I posted earlier is also looking like a possibility. I'm hoping to hear from some of the folks here to see if anyone has any thoughts on the route.
Start at Santa Monica Pier (Route 66 terminus)
Take Bicycle Route 66 to Marshfield, MO
Take TransAm Route to Doswell, VA
Take Atlantic Coast Route to Bridgeport, PA
Take Chicago to NYC Philadelphia Alternate to Brooklyn, NY
Finish in Brooklyn, NYAgain, thanks so much for all your extremely helpful thoughts on our journey. It's very much appreciated. And, thanks for the direct email. If you prefer I can contact you that way. Mine is megmtb(at)gmail(dot)com.
