Just got back from a ride through Summit and the reservation this afternoon. The biking around there is, sadly, not so great, though the reservation is a nice few miles. Lots of stoplights and cars. There's nothing like the C&O Canal. But if you pedal west you fight through suburban glom for half and hour or so and then you can get to the Somerset Hills area, which is fantastically beautiful and very good riding. If you are willing to drive, there is good biking all through the western part of the state within an hour. As for commuting, you can lock up at the station and train it into NYC, or take a folder, which I highly recommend as speeding through Manhattan has a video-game quality not found elsewhere.
