We'll be camping here on Saturday, probably arriving about 10 or so and then heading into the woods:
We'll have our FRS radios on channel 10-15 if there's too much traffic in the area.
Forget the maps the park service puts out-they're useless. If you really want to find the roads and not go around in circles out there, get a GPS and get on www.gpsfiledepot.com
where you can search for topographic map data for New Jersey. This way, any road that has existed within the past 75 years or so will show up on your GPS. Some of them won't be passable in a vehicle, but some will depending on how much you care about your paint job. Also, you can plot waypoints in Garmin Basecamp so that you don't have to spend hours and $$$ in gas trying to find a particular spot.
