What did you do when teenagers no longer want to camp?

Cryonic Freeze! My girls stopped wanting to go about the time they were of age to be left home alone. We kept them going a bit longer by staying near places that they'd like (somewhat close to a mall or shopping, they must have caught that disease from mom). When we started leaving them home, we put cameras in the house so they knew they can't get away with any shenanigans.
