Well, I just got back from camping in New Jersey. The campground we've been visiting for the past three years has a new policy: no bicycles. They've been operating since 1954 with no problems but last year there were two claims made and the insurance company told the campground to get rid of the bikes. In addition, a whole range of activities have new restrictions such that (for example) my kid can't go feed animals at the farm without an adult present. Or play billards. Or rent sports equipment.
The place had a lifelessness without kids biking around. Plus, I noticed quite a few of the seasonal campers (those who leave their RVs at the campground all summer) had packed up, leaving empty spaces. It's a shame.
