I was thinking about this recently, I think it was because I heard that creepy secret society Dialog was doing it and I thought "ok that actually sounds pretty cool without all the extra cult bullshit."
Basically iirc they have a matchmaking summer camp for adults (like to find a romantic partner), but removed from the Theil cult stuff A) that's a good idea on it's own, and B) it doesn't have to be for meeting people, just for fun, and you can still meet people if it so happens.
Could have all kinds of arts and crafts, canoes and shit, fishing, hide and seek, scavenger hunts, cabins and lunches (etc) just like kids camps but bigger, archery and a (controlled) rifle range, nature walks, classes on plant ID and uses, building cool shit like rope swings (and that's free labor to help expand the camp), etc! Counselors can be volunteers so poors like me could attend in exchange for working it, you could have themed ones and keep it running almost year round with some set-up for the next in between (like, 2w normal, 2w sober/recovery, 2w LGBT, 2w Clue [solve the fake murder], 2w Spooooky halloween, 2w Winter Wonderland, etc), I'd rather go in the fall personally for instance because I like the weather even without a theme.
Idk it could be a fun time.
