OC'd at Lowe's... got helped by a couple of staff members... one to point me in the direction of what I was looking to buy... the other to help me select what I needed.. I don't believe either noticed my sidearm... 2 employees came by with one of the fork trucks and a younger guy pointed and said "alright, I see you support OC"... I didn't exactly like him "exposing" me.. but everything was still all good. The guy helping me went and got a cart for me to put the large item into, I went to the front, paid, all good. No looks, no stares, nuttin except the one guy who thought it was cool I was OCing. Walked by a lots of people and no one noticed... though when walking by a couple of families with younger kids, I tried to keep strong side away from them just to be respectful of the children.
Also, earlier in the day I had went into a local gun shop and my dad had been in there a couple of days before. Apparently they were discussing me OCing.. gun shop owner said he knows a guy who got 2 cops to draw guns at him in Menard's... they apparently didn't arrest him, but detained him for a period, and as I said had drawn on him. Apparently this was 1-1.5 years ago. I showed him MSP update 86 and the LPD memo. He said he still didn't think it was a good idea, but he sees how people would want to do combos of OC and CC...
carry on!
