Just to see the cart in action again.
Most bullpen carts were of the same basic design: a cap for the top painted like the home team, a baseball for the sides and front with two pillars that looked like bats supporting the bill of the cap. The Diamondbacks' cart is designed accordingly.
There were some outliers, though. The Yankees had the douchiest system of all with a pin-striped sedan to deliver the pitcher and the Mariners had the goofiest with a tugboat.
If the Astros adopt the bullpen cart, should it be conventional, or one of the more creative types? Perhaps a train, or a rocket? How about a ROCKET TRAIN!! The driver could be wearing a space suit and a conductor's hat.
