I may have mentioned this trail before. There is an extension of this trail just behind my house. I can get on there and ride almost all the way to Washington DC 334 miles (554km) on trail. At most 5% is roads and they are just some back country roads.
I have done the whole thing once and from Pittsburgh to Cumberland twice. But I ride bits of it several times each year.
