LOL!
It's almost fishing season, here. I was talking with Anoreth this evening about arranging a fishing (and other outdoor stuff) trip for her and her friends from church. Our big county park has fishing, swimming, boating, hiking, cookout ... all kinds of things teens can do if they're dropped off in the morning and picked up by dark. And the cost is $5 a carload, iirc.
I'll assume they charge you when you drop them off, not when you are supposed to pick them up.
