We have been participating in the Mystery Class hunt for five years now. I think it’s five. Could it be six? Five or six, it’s been a blast every time.
Here’s a post I wrote about it two years ago (full of nuts & bolts info).
Things don’t really get rolling until this Friday, when the first set of clues come out, so you’ve got plenty of time to sign up at the Journey North website. (It’s free.) It’s way fun.
