Tommy, I realize that it's probably tough around the denser populated areas.
But, we spent about 3 weeks north of here in the latter part of Sept. into the first part of Oct. The campground was never full, and some nights we were the only ones there.
Now I will add this place probably wouldn't be for everyone. They didn't have full hookups, only electric. There was showers, potable water spigot, vault toilets, and everything was kept clean. Price was right too. $25 a night or $125 a week.
