Pick up the drums with a forklift and set the idiots on the side of the ride.
They can watch the traffic go by while they freeze their asses off.
I was thinking the same thing. A front end loader would do the trick. If they get maimed in the process, BFD. Playing on the freeway, expect to get hurt.
Chainsaw would be quicker.
Hose them down first, helps with the attitude adjustment.
