We will see FW for the first time in October... but until then, our favorite campground is right around the corner from us, Hammonassette State Park in Connecticut:

Dry camping, huge flat open sites, beach, bike riding, bird watching, nature center... just a great park all around, for not a lot of money.
We have been to a lot of private campgrounds in our area, but our favorite is probably River Bend Campground in Oneco, CT:

Might be a little rustic for some, sites aren't the biggest, but the staff is great, ALL the campers we've met there are wonderful, and we've always just had a great time while camping there.
Fort Wilderness, we'll see you in 3 months! (CRIPES, that soon already?? I gotta go start packing...)
