If you're pulled over and are late for something, just say so! I'm sure the cop(s) would understand. However, taking a couple minutes of your time now is liable to get you out of a ticket or two later!
Once I get mine, I'm taking it to the PD so that ALL the town cops can see it

. It's a small town, and my father's a sergeant. Just about all the guys and gals in the department are gearheads, so I know they'll enjoy seeing it up close. Cops are people too!
