I live in a small town, well compared to cities, its about 40,000 people. I still carry in the right front. After going to Chicago, and watching some guy TRY to pick my granfathers rear pocket, I started carrying in the front. Of course the pick pocket didn't fair to well against a 70 year old man. The kid was maybe 19-22, and it was getting onto the train, he went in to get the wallet and my granfather felt it. He turned, grabbed the kids wrist an made the kid drop the wallet. It was then that he twisted the kids arm behind his back and dropped him to the ground. Then the security guards showed up, and the arrested the kid.
I guess you don't mess with old codgers from Montana... the guy is still one tough mofo.
