Pranks are STILL part of the program. There was a team last year here in Vegas that locked their golf cart with a chain thru the rear wheels on the trailer on Friday night. Team gets back to the track on Saturday, golf cart is gone but the chain was still there, locked just like they left it. Ask around the pits, nobody has any idea what happened (of course). Team comes back to the track Sunday and the golf cart is locked to rear axle of the trailer ... Just like they left it Friday night.
