Starting to think about a trans-continental tour of North America. The default route could be ACA's
TransAmerica, which is referred to as a classic.
I am unfamiliar with the US network of great cycling routes, but noticed that this classic doesn't use the Katy Trail, and doesn't seem to ride the Blue Ridge parkway either.
Can this classic be improved? The idea isn't to do it as fast as possible, but rather to ride where riding is best, to stop here and there to visit cities or national parks, and to take the weather into consideration. Maybe using historic routes. Possibilities are practically endless.
Suggestions?
