Big Katuna ,
Total and complete BULL. I'll give you just one name of just one of the many RV parks closed in the area during the summer months. Old Town Campground and Retreat. Call them and try to get a site this summer and please report back honestly if you dare. Better keep a towel handy so you can wipe the egg off your face! I already know the answer and for several others too as I know the owners personally and NO, they are not our family's owned CG's either.
Perhaps, you might just drive past the entrance and see the lock entrance gate and the sign. Might want to check other CG's also and be sure to take that towel as you'll need it and maybe several more depending on how cleanly you want to wipe the eggs off your face!
Heard more than enough of you know-it-all posters!
