I don't know, i'd think low cost motels and strippers might be amenities to some of us bike tourists.

Just saying, and kind of off topic.
On topic, however, knowing maps and studied geography/GIS at university, I think the ACA maps some of the best cycling geared resources available to bike tourists. Wholeheartedly recommend.
A caveat, I've only used them as at home resources to pick the best roads to ride on, but would bring them with in a heartbeat if i were to ride the northern/souther tier, other main routes, or explore their themed tours.
