I was viewing Crystal Lake activity on a warm sunny day this week, noting tons of children, teenagers and young adults mixing in close proximity. And that was just in the bath house, beach, and formal swimming area. I was to left to wonder whether it is better to open the bath house, beach, docks, and swimming area with strict rules and enforcement, or keep it closed with no rules and lack of enforcement. There’s no way for the police to maintain active supervision in this setting. In contrast, if there were many Parks and Rec staff people on duty, enforcement might be more effective.
And, yes, the other access and grassy spots are a separate problem. An intractable one, I’d guess.
