I am only here on the weekends but I have been open carrying and thought it would be a useful for others to catalog where I have open carried and any reactions:
Target on Robert St in West St Paul
Walmart on Robert St in West St Paul
Cub Foods on Robert St in West St Paul
Noodles & Company on Robert St in West St Paul (a LOT because I love their food)
Macy's at Mall of America (I know that MOA bans guns but the Macy's entrance didn't and they were more than willing to let me spend a few hundred on shirts and ties)
Office Max in Eagan
Barnes & Noble on Hamline Ave in St Paul
WalMart on Hamline Ave in St Paul
Actually, I have had amazingly few reactions. In Target the other night, one of the other customers (an hispanic man) asked me if it was a real gun and was amazed when I told him it was. And the greeter at WalMart looked at me funny as I was leaving once but otherwise, no one has said a thing.
The manager at Office Max helped me find everything to furnish my local office and she noticed the gun early in my time there but didn't say a thing.
I found this to be an interesting post. Welcome to Minnesota, and I see by your bio you might just be hanging around for a while. Every once in awhile I check out your website and find it interesting, but disappointing that there aren't many post from Minnesota. Also interesting is that you live in the Bristol area, my brother and his family live in Abingdon and I'm familiar with the area and have been in Bristol several times.
If your in town this weekend and looking for something to do, this is the big weekend for Alhmans. http://www.ahlmans.com/ You won't find another gun shop/range like it anywhere, and the Shooters Roundup draws a big crowd. Would be a good place to set up a booth and promote your website.
