Last year, 100 teams participated in this five mile race where costumed participants pull shopping carts from Brooklyn to Manhattan to win "sacks of cash". There are two mandatory checkpoints (usually bars -- drinking is encouraged), but otherwise the rules are lax: you can commit any act of nonviolent sabotage, from oil slicks to padlocking junk onto competitors' carts. The organizers are cagey about the specifics (they'll announce the start/finish points on Monday), but we wanted to tip you off early -- you'll need a week to weld the feces cannon onto your rig.
