NewMindSpace presented their Subway Parties at TransitCamp and their experience with organizing parties on public transport. Subway parties have been around for awhile but they’ve been using the web and technology to organize them. They try to provide limited notice of the party to avoid more than 250 people filling a subway car. They also get on the last train to avoid causing problems for people and bring a portable music system. They’ve also organized the Pirates of the Street Car party. You can see the Ridethereindeer subway party and with video. I’ve followed a few other there events and I’ve always been impressed with how many people they get out to their events.
