I spent a lot of time at Red Wing lakes in Port Republic, and will go back soon. Wading pines is great too, it's close to Batsto.
I love Shanondoa, Skyline drive, Smokey Mountains and everything in between. Smith Mountain Lake is pretty cool, and when I was there, they had these cute ranger chicks that like to walk around the park after their shifts.
Also, one of the coolest places I ever camped at was in Tennasee. I forget the name of the place but it was in Polk County, which is south east Tenn. I only spent one night there after a run in with the law, but I want to go back badly. The cops actually clued me in to the place. Kinda wanna go back there and visit them too, and tell them about all the stuff they didn't (but should have) gotten me for.
I have actually camped in every state on the east coast and into Canada, several southern states too. Alabama was nice. I stayed at pine bluffs for a few days, and they sent me christmas cards for a while.
Anyways, I like to camp out and only do primative style. I can't stand when people call sleepig in a camper or rv camping. That's a hotel in the woods.
Getting back to NJ, I think I preferr Red Wings Lake, but I know ther are lots of cool spots. I went to one in Sea Isle 2 years ago, that had a small water park. It was great for the little ones, plus they had a nice lake for boating and fishing.
Let me know if you know of any cool spots in south east PA. I have only been to marsh creek. I know there are tons of places, up north. I spent a few Thanksgivings up in Tioga and that area, also Potter county.
Sorry for the long, rambling off topic post, but that's my style these days.
