It's always cool to see these beasts in action. The Monster Jam is this weekend at the US Cellular Center in Downtown Cedar Rapids. I caught up with John Zimmer this morning. He's a driver on the circuit who usually commandeers The Gravedigger. This weekend he's at the wheel of the Monster Energy rig. Here's a peek inside this awesome machine.

Enjoy the pit party and get more on the Jam right here. Should be a crusher of a weekend at the Cell!
