Thanks for the link. I think it will be helpful. Do you know if there's a similar bicycle network in Ohio? It would be nice if Ohio had just picked up the end of Pennsylvania's Route V and continued west. I'll need a way of getting from the end of Pennsylvania's Route V to the Underground Railroad route near Akron. I prefer to not have to go north to Erie PA just to head south toward Sandusky.
Let me know if you decide on Route V. In 2014 I rode it W-E between Emlenton and Catawissa/Bloomsburg, camping and cooking. Route V is well signed. I am a low-tech guy so I also made up cue sheets, especially since I had to go off route a short distance in a few places to find camping. I started at the Youngstown-Warren Regional Airport, took my own route to Franklin, PA and then picked up the Allegheny River Trail, which is quite nice (and paved), to Emlenton to join Route V. The section of the route between the start and Franklin was nice with little traffic until Franklin. Right outside of Franklin there is free riverside camping (first-come, first served) along the trail that has tent pads and two, small Adirondack Shelters. No water, but there are porta-potties, and it's a quick ride into the center of town for groceries. Saw a pair of young bald eagles in the morning.
The airport is not that far from Akron. Google Maps bike directions returns a route of 53 miles to downtown Akron with very little climbing. It goes past a state park (West Branch) that has camping.
Where in N. Jersey are you planning on starting? One option is to take the train to Port Jervis, ride through the Delaware Water Gap N.R.A. and hook up with Route V in Milford, PA.
Update: Just checked my RWGPS files. I have maps for each day from Warren to Bloomsburg that include the off route sections to campgrounds. They are, of course, made for the opposite direction, but they still show where the camping is and the elevation profiles. (In my memory I have a few other campgrounds I passed.)
