Butler maps are really nice--expensive?--not really, given their quality and the R&D involved in putting them together. Try pricing Nautical Charts (which are mandatory if you sail) I have discovered maps put out by Adventure Cycling Association. These are maps that designate trips like Bar Harbor, Maine to Seattle WA, Bar Harbor to Key West FL, and everything inbetween. What is nice about these routes is that they steer clear of fast highways, heavy traffic, etc. and concentrate on scenic and safe. That is the ticket for a motorcycle. They show campgrounds and stuff relevant to bicycling. For gas stations and motel facilities you need to use your Smart Phone.
