Check out the Army Corp of Engineers campgrounds in your area. Many are located right near the water's edge, and space between campsites is generally greater than you'll find in a private campground. We're retired, and use the Senior Pass at the Corp locations. Ten bucks a night is hard to beat. Generally, you'll need to fill the fresh tank on the way in, and dump your tanks on the way out, but electrical service has been excellent in all we've stayed at. Important, too, the rangers patrol the parks methodically, the restrooms and showers are kept clean, fire pits are routinely cleaned, and mowing is up to par. The ones we frequent offer paved roads, shade trees, and long spaces. On weekends (at least before Labor Day), the rangers put on a variety of interesting walks and discussions. As with any park, amenities will vary by location.
We'll be camping this entire month. With all the kids back in school, it's usually just us 'old timers' ruling the parks these days! Oh, the joys of retirement!
Hope you have a wonderful time!
