They really, really hate it if you camp here. They'll take your money (eventually, if anyone shows up, there's no drop box to self-pay, there's no online option for the primitive sites, no camp host, and no one answers any of the phone numbers), insult you to your face repeatedly (the norm for Peoria), and then call the sheriff on you (just to come by and insult you more…?) for camping for a week at their campsite (very quietly, intentionally bothering no one, just camping to get some alone time and be left alone in peace). Horrible people.
PS, for solo lady travelers: they're all the dehumanzing "good ole boys" type here, so be ready to have to deal with that (they'll call the sheriff if you don't play the damsel in distress they want, it's messed up)
