Team Sheldrake, i.e. Luke, Joe, maxistentialist and myself, kicked ass at DASH 4 this weekend. Hats off to James and Wil and the other organizers across the country who did an incredible job. Every one of the puzzles was its own little masterpiece. The whole event, which is entirely volunteer-run, takes eight months to organize, and it shows.
If this kind of thing appeals to you, I suggest you sign up for their mailing list to find out about future hunts, in Chicago and across the country.
