Just Another Square in a Wide-Brimmed Hat.
Jake of Zoomdoggle is scruffy and cute, so you must love him. Do everything he says. In this case, find the 8000 Indiana Jones hats he and his friends have hidden all over LA, and take pictures of yourself being just as animated and ironic as he is. (Don't forget to tag them!)
Adrants reader Jay notes this apparently casual scavenger hunt was announced the same day Indiana Jones and the Kingdom of the Crystal Skull came out on DVD, so he's pegged it as a below-the-radar marketing ploy. "Wonder what they're going to do with all the pictures," he ruminates suggestively.
I'm sure we'll all find out.
UPDATE: Cunning's 'fessed to using Jake and Friends as vehicles for an over-arching Indiana Jones promotion. (Not in so many words, but I feel my assumptions are safe -- or if not, they'll be corrected with lightning speed. See comments.)
