I belong to a Facebook RV group (or 5) and ... as a newbie, have found them VERY informative. Most of them also post photos of various places they've been or of issues they've had with their campers, etc. Here's a pic some dude took in a campground with a "WTF?" heading! I figure he must'a been snooping around P-hole's driveway.
