Ride bikes and watch Marty McFly

Grab 1-3 friends and head to Whittier Park Sunday for the starting line of this free, 75-clue bike scavenger hunt that'll take you across the TCs "past, present, and future", culminating with a 730p showing of Back To The Future III under the 10th Ave bridge, so where you're going, you don't need roads! Just mace to protect yourself from hobos.
