RE: Philly area CG's ???
The bad: For the most part the campgrounds in the mid-west/eastern U.S. are poor. They were opened years ago for campers to park a trailer for summer get aways. They are often off the beaten path and usally situated on a old stinky lake miles from the nearest city. The good: Last spring I stayed in Lancaster, Pa at the Country Acres RV, fullhookups with cable, $36, and it was a nice campground. However, it was about 80 miles from Philadelphia. They did have a great little diner about 2mi West of the Park. We drove to Philidelphia for a day trip and I don't remember seeing another RV park along the way.
