Pay it. If you've never seen the denver parking guys in action, you'll get to see it first hand. This is the one thing they do with speed and precision. I saw a van scan plates. slam on th brakes and have the boot on in under 60 seconds. On the same note, a co-worker in a utility truck pulled over to talk to dispatch, got a street sweeping ticket while in his truck. She could have just as easily asked him to move. He was in the truck. He thinks he's gonna fight it and win. Silly youth.
