We called it quits a little before 2 AM. We were all pretty burned out, and we figured that the hunt would likely be over by the time we go back from sleeping, anyway (it looks like it's possibly still going on but very close to the endgame). We had a lot of fun, and we ended up solving 9 puzzles (of course, 2 of those were freebies, but that's OK). I think we're all fairly excited about doing this next year, and I would like to try looking into the hunt archives and digging into some mini-hunts, hopefully as a team. We definitely need more people next year, though; if not, I will likely try to attach myself to another team.
Now off to a brunch date. I hope I'm able to be coherent.
