5. I just realized how important warm showers org. is! Its okay to cover 100 miles in 10 days.
But, what if things do not go as one plans! It could be 20 or 30 days instead! That adds up.
Huh? I am not sure what you are saying here. Care to clarify?
FWIW: Warm showers is great, but on any of the routes I have ridden you would be lucky to find a host on your route once every two or three weeks. So unless you plan the route specifically around warm shower host locations they will probably be a once in a while thing.
That said on the Trans America we managed to stay for free or real cheap most of the time between city/town parks, churches, hiker/biker sites, and hosts we met along the way without the need for warm showers hosts. Most of the time we were in our tent, but a few folks offered us a bed or a floor including several churches who let us stay indoors.
On my Spring tour this year I camped for free a bit more than half the time (several town parks and one church yard). Since the motels were really reasonably priced in Kansas and Oklahoma and there was a thunderstorm about the time I rolled into town several evenings, the rest of the time I stayed in reasonably priced motels. The nights that I got a room I am sure I could have found a free place to stay if I had looked/asked around.
In the middle of the country I found that there was seldom a problem just pitching a tent in the town park, but if I had the chance I usually asked the local police for advice. Sometimes the local librarian, the clerk at the minimart, someone at the local church, or someone at the local firehouse will point you to a place you can stay and not be bothered.
