My only experience in a place like that was a few years ago when we camped at "Bob's" for the Bristol night race. For the uninitiated, Bobs is famous for roudy loud and ???able behavior during this Nascar weekend. Don't know the totals but there are countless rvs scattered in a loosely laid out pattern over several acres of basically pasture land. Sites are small, primitive, and not well defined like you would expect in a campground. It is a place that I would never show up late and for sure would never arrive after dark.
Once was enough and there is nothing that would attract us to a place like that again, country music, blues, bluegrass or people passing out $100 bills. You are very lucky you didn't damage your TT.
