Wanna check mine at the French Lick casino. Left my H&K P7 in the vehicle last week.
Just haven't witnessed anyone else doing so, and I haven't noticed any storage facilities near turnstiles. Guess I'll ask.
As soon as your going thru the turnstiles look to your left. There is a door.. Inside that little office, they have 4 lock boxes.. They hardly ever get used.. There has been times when I sign my gun in that I notice I was the last one to sign out on the paper and it was over a 2 week period..
You just tell the security at the turnstile and they will get you taken care of.
