- NYC to Albany
- Albany to Buffalo
- ACA maps (Underground Railroad -> TransAmerica -> Western Express)
I'm going north first because it'll bypass a lot of the hilliness crossing the Appalachians and Albany to Buffalo is 380 miles of mostly bike paths tracking the Erie Canal.
The hardest part, I think, will be the Western Express (everything after Pueblo, CO). This will be largely unpopulated desert. I've got 7 water bottles expandable to 10, which should be enough to get me from town to town, and other than that, it's just preparation: repair gear and proper clothing (cotton during the day to avoid dehydration, synthetics at night to avoid hypothermia).
Here's a really big map (3MB):
