Full Throttle Saloon -- Burns To The Ground

The world's largest biker bar -- Full Throttle Saloon -- burned to the ground early Tuesday morning.

The South Dakota landmark bar was the central watering hole for hundreds of thousands of bikers who show up every year for the Sturgis Motorcycle Rally. It's also where the truTV series, "Full Throttle Saloon" was shot during the rally.

No word on rebuilding or where the series will be shot. The cause of the fire is still under investigation.
