The local bike shop in Hackettstown, Marty's Reliable Cycle, has been organizing rides on Sunday mornings. It's a nice group and the routes, thus far, have been within Warren County which is one of the most rural counties in New Jersey. That translates into rides on quiet roads. The "Skyland Region" of New Jersey, in blue in the map above, is great for cycling.
