It might be a good idea to have a copy of the MN law about the mirror, since local police won't know it.
Nice work at not getting any tickets, I'm guessing they see your out of state and don't make a huge fuss over it. I have not been pulled over since I have done my mods, but have been followed a couple of times. Kind of shocked I wasn't pulled over since I was going 45mph in a 55 zone for some off the wall reasion like they thought I'm drunk or something. On a side note, I have been getting people saying "I like your hubcaps" quite a bit now
