Just go down to s.w. Ga there are 1000’s of miles of dirt roads—-cabins were more expensive than the local state park lodge, plus shared bathhouse. I have no problem but my 5 year old isn't gonna want to go out there at night to pee, nor do I want to go with him.
also SxS rentals are crazy expensive! Like $600 for the day. I'm not looking to get wild mudding, just hit some dirt roads and whatever. I imagine the trails I take are all passable in a minivan, but the kids will see it as an "offroad adventure"
