Hitting San Diego for the first time this Saturday, Gorilla Challenge is
just a reference to playing Mario Kart as Donkey Kong and still being able to jump the ramp with enough speed to hit the secret waterfall cave in Koopa Troopa Beach an individual or team-driven, camera-friendly, free-form race permitting the use of public transportation (cabs don't count), which refers to itself as a cross between Amazing Race, Fear Factor, and American Idol, and is open to everyone except "Goa'uld, members of the Dark Side, Borgs, and Zombies", so, sorry make-believe people and Rob.
Speed racers start off by grabbing a game card with cryptic clues leading to 12 different points (spread in a 3-5mi radius from the starting point) where another clue awaits, directing sleuths to do things like sing to strangers, root around in nasty substances for another clue, and take pictures in "silly to crazy poses", as "silly to crazy posers" would just invite C. Thomas Howell from Soul Man, and no one wants that. Past acts of zaniness have involved things like publicly denouncing a certain Ecuador-ruining oil company on their front doorstep, and taking a picture with an old-dude statue situated at the crossing of roads named after Isaac Newton's fruit and one of the most famous battles in Texas history, which seems pretty simple until you realize Tomato Street and That-Time-Walker-Texas-Ranger-Took-Down-that-Moonshine-Ring Avenue actually run parallel.
For added motivation, certain stops will have gift cards thrown in with the clue, and they're also giving out Lil Wayne-style cash money to the first three teams to finish, the team who brings the most non-perishable food items for the SD Food Bank, and the advanced primate with the best costume, though throwing on your old Kong get-up doesn't exactly scream, "I'mma gonna winnn".
