Hummers? I don't know...
At the last minute I was told to drive an LMTV (below) instead. They REALLY suck in the cornering department, but on the plus side they have a HUGE amount of turbo deisel torque. And even though it's an 7 speed auto it's still fun to hear all that boost spooling under the cab. When you're really bored in the desert that is... and when I'm extremely bored sometime I rev the engine up then hit the air brake to simulate a bov.
