Just before I flew to Seattle for the Every Building Conference & Expo this morning, I read about a very unusual challenge being run by Schlage, coincidentally also in Seattle. With his consent, they locked a guy named Joshua in a tiny house (174 square feet), and it's up to the locals to follow clues, find the key, and set Joshua free. The first person to find the key and let Joshua out wins $5,000! There are prizes for the 10 runners up as well. I couldn't pass up the opportunity to go see this crazy guy Joshua, so it was my first stop upon arrival.
