I've reserved a campsite at Round Valley Recreation Area for this coming labor day weekend. The trick here is that the site is three miles from the parking area.
The obvious thought is to take along bikes and haul stuff to the site. Hoewver, we only have one bike with full-sized racks on it. The plan is car-camping, so there will be a lot more camping stuff than I normally take on a bike tour. Is there anywhere in NJ you can rent a bike trailer?
