OC'ed all weekend while in MI (From FL)
OC'ed at Lowes / Home depot in Commerce Township... no problems there...
OC'ed on Mackinac Island... had one or two looks, but nothing much...
OC'ed at Leo's Coney Island, Meijers Commerce Township, no issues. Then I went into Walmart to buy some 12ga and 308ammo for a quick visit to a range. Got the ammo no problem, but while I was at the checkout in the sports area the guy (Joe) made a comment about my sidearm asking if I was in there a week ago and they gave me a problem. I stated that I was not, however it was perfectly legal. Conversation went back and forth, with him telling me he was a retired cop, and that city law was higher then state law. Thankfully when I OC, I print out a copy of the MSP Update and the preemption law. I nicely corrected him, and explained some of our gun laws briefly. Went on my way to the Pontiac state park gun range, and they did not have a problem with OC, just informed me I was not allowed to shoot my pistol as it was not cased (which was fine with me because it had JHP rounds that are to expensive to shoot everyday)
