Carson City Costco says NO!!!
Wanted to do some shopping there today, but before I went, I called and asked for the Store Manager on duty. His name is Wes Camp, so he told me. Anyhow, he gets on the line and I'm being extremely polite and respectful, as always, and I informed him I was a member there, and also buy for my business as well and that I wanted to know what their OC policy was, and are they OC friendly?
He said, are you a LEO? I said no, I am a member there. He said unless you are a LEO, absolutely no firearms allowed. I said, "really, I didn't notice any signs posted saying such, are you aware of that"? He said it doesn't matter, it's our store policy.
So I go down there, no OC and get their corporate number. We'll see what happens.
