Just returned from a four day series of father/son day trips in Virgina that unexpectedly spilled into DC. I was amazed by the quality and quantity of bike paths in and around DC. We apparently just scratched the surface riding around the monuments and Rock Creek, but are planning a return trip with the rest of the family in August for more DC riding as well as hitting the C&O. Any suggestions on routes and camping ? We originally planned a Washington-Pittsburgh tour, but I think spending more time in DC and car-hopping might be more interesting.
