Patrick,
I saw this story on Drudge yesterday and almost fell out of my chair when you were quoted near the end!
Just for the record I have never lock my locker either. Yet, I never leave my wallet in there, just shoes, hats, balls and bric a brac that no-one would ever want.
Given the dog eat dog, betting nature of your Dad's world I am sure you were taught to keep the wallet close at all times.
