Window tint(where to get it)

Iowa laws sux around here . We have a lot of new cops trying to impress each other and they interpret the laws as they see fit at the time. Sometimes they will be ok with something and the next time they cite ya for it. I have been pulled over by old cops who just want to see the car up close and young cops who want to make ticket quota and run a 45 minute inspection on the car and hand me a stack of tickets and tell me next time we impound it . (they expect me to thank them for being so generous) I've beaten the tickets everytime (I was a state inspector when we had inspections) Just a pain in the ***.
