I think someone once told me that it's easy to get your pocket picked if it's in the back. Not so much in front. Not that there's a big pocket-picking issue where I hang outBut I don't like sitting on it anyway.
My wallet goes in the front as well if I don't have a coat/hoodie on that has pockets. I refuse to sit on my wallet as well. Once I get in my vehicle it goes into the counsel.
