So I just found out that there is a trail across America called the American Discovery Trail. Supposedly you can go across the USA on a bike using nothing (or almost nothing) but trails. Trails for only non motorized vehicles. I have seen many videos ans blogs about the ACA and other routes across the US, but this is a new one to me. Has anyone ever done this? Is it really possible to cross the US on trails only? Any info will be appreciated.
