Bring alcohol, bring a silly hat, bring a DVD you no longer want and be ready for absolutely anything at Mystery Trip. Birthday parties and corporate groups hire guide Mysterious Dave for a full day of drunken revelry, zigzagging across the city in a Technicolor dream bus with no sense of where they're going next (Dodger Stadium? The Bunny Museum?) and what will be asked of them (scavenger hunts, dance routines and cheesy bonding games, oh my). Taking inspiration from his fond memories from sleep-away camp of hopping on a bus for unknown adventures, Mysterious Dave combs an extensive database to customize for each group a tour of wacky destinations, treats, competitions and meals in Los Angeles. All you have to do is show up. (310) 650-5656, facebook.com/MysteryTripLA.
