Still sore from Journey to the End of the Night on Saturday, which was the most fun I've had in ages. It's essentially zombie tag (become a tagger when tagged) with thousands of people across an urban area.We started in SF's Fort Mason as 'nominees' and had to collect 'voter sponsorships' from 'focus groups' ranging from Coit Tower to the Presidio. They had fun little exercises set up at each place for you to win their votes, and an overall quirky, fun vibe.Sprinting through the city keeping an eye out for other players kept you on edge. There were several fun moments when we eyed each other across the street, then broke into sprints at the same time to try and escape. You were always checking your back, always peeking around corners.Not much to improve here, except maybe using technology a bit more. Could be fun to have moments when you could see everyone on the map, or a running leaderboard on top taggers and the like. I felt so alive! My legs are still paying for all that sprinting days later, though...
