The reason I chose our state parks (crowded as they are) over some of the other parks is that the state parks tend to have actual security. I used to boondock or go to primitive camps and, particularly during the big meth lab years (15 years ago or so), that could be fairly scary. Lately with the increase of homeless and "homefree" travelers, I prefer the security of a campground with several hosts.
Plus, camping in a campground with electrical hookups means no "generator symphony" from 7am to 10pm. (Although 2 weeks ago my camping neighbor with a big diesel pusher found the campground's 30amp service inadequate to run his A/C and his big outdoor entertainment system and fired up his diesel generator - the one with the exhaust pointed right at our camp. A few calm but pointed words ended that. I'd have had zero problem going for a campground host if that hadn't worked)
I don't mind the kids in camp, although I always look at the maps and try to pick a campsite that isn't near the playgrounds or bike paths. The problem is always the adults who should know better.
Yes, making reservations well in advance is a pain, but then our schedule is looser than many and we can usually find something mid-week. My favorite campground at the coast is currently booking June dates for 2017 - they will be booking July 2017 dates in Oct 2016, which is when I will reserve our annual 10 days at the beach.
