So I've already spent all of money (basically my budget) for my bike, parts, and equipment. Trying to decide my route now (starting in the Northwest...ending in San Diego...I might bike first to East coast like near New York City). I was going to get the Adventure Cycling Routes but the paper maps are just a bit to expensive for me. Plus I would rather use something that works with my iPhone. I considered using the GPS waypoints (found some at this site) but the paths don't line up to the road/paths that great (I compared it to the one paper map I bought from Adventure Cyclists). So I am looking at the alternatives.
Could I just ride the interstates all the way through? Are the shoulders big enough?
Has anyone tried Google Map's bike directions (looks like lots of back roads)?
Finally, what did other people do who toured coast-to-coast?
