In a sure sign that San Francisco is a place where, if you can dream it, you can find five other guys to help you pull it off.

A group of hard-core Indiana Jones fans created a life-size boulder out of 5 million legos and let it loose on the streets of San Francisco.

Kotaku thinks this my be another viral marketing ad. Possibly for the Indiana Jones Lego game coming from Lucas Arts. Does anyone who lives in the city remember this being filmed? Tell us in the comments.

A Kotaku commenter stated the video is real;

"Guess what people... that s**t was all real. the Indy running down the hill is oakland artist and one of the funniest people ever, Pete Grenquist, who coincidentally was on Kotaku a week ago in their article about the designer PacMan grenades.
believe me...
NO Permits
NO assistance from lego
Just a bunch of funny SF f***ers with criminal mischief inclinations and a lot of free time.
What else would you expect from the home of Burning Man??"

This is why I'm selling my car, wayward Lego boulders.
