This business got started by a couple of acquaintances of mine, and looks pretty interesting. If I ever do this, I want to take a few of the most gifted puzzle solvers that I can find with me, which is why I'm bringing this up here
If there's some interest, let me know, and maybe we can set it up as an event. It's $20 per person, the minimum age to participate is 14, and the maximum group size is 8.
It does not appear to be a scary activity, although the concept definitely sounds like one of the Saw movies.
