According to press notes, the hunt will work this way: "Working in teams of four or five, players will race around Los Angeles to defeat a fictional Ballot Proposition, deciphering clues provided primarily through videos featuring a wide variety of celebrities, including Neil Patrick Harris, Kristin Chenoweth, Jeff Probst, Steven Weber and others."

LARF's co-founder, Bob Glouberman, said in a statement, "We thought it would be fun to engage racers in a satirical look at the inequality created by California's Proposition 8 by focusing on a completely fictitious Ballot Measure – Prop 8A – that would prevent our hero, conveniently named 'LARF,' from marrying. It's going to be a great interactive experience: racers will get a unique combination of three elements – a humorous look at the subject matter, brain-busting clues, and an amazing array of celebrities in the filmed clues."

Others set to take part in the filmed clues include Anthony LaPaglia, Kathy Najimy, Camryn Manheim and more.

Proceeds from the event will go to the Williams Institute at UCLA Law School, a think tank devoted to non-partisan research and education on law and public policy related to sexual orientation.
