We were at the national park about two weeks ago. It was fairly warm, low 80s and sunny. We were camped up north at the Indian River Inlet, but did several trips south to ride our bikes in the park. We rode all of the campground roads a few times. I was surprised by several things. First, there was very little generator use, or anybody at their campsites, mid-day. Second there is a no generator loop. Third, there was a real mix of rigs with a lot of huge TTs, fifths, and class As, mixed in with the folks who were in tents. Finally, the sites on the ocean side were quite loud from the surf, and the sites were far apart. Unless some moron was on the next site with a 5500 open frame genny, and it was dead quiet, It would be tough to really suffer from somebody else's genny noise, or at least as bad as it gets in some other no-hookup situations.
