World Urban Polo Championship Scavenger Hunt & Pub Crawl

Okay, there's no polo, per se, but you will be competing in "polo-themed" challenges to try to win the scavenger hunt–pub crawl, which features a $500 grand prize. In addition to a ticket, to participate you'll need a team of two to four friends, a MetroCard and an iPhone, to look up clues on the event's app.
