Damn Van, that really blows. You are the 2nd person who I've heard from that's gotten their bag ganked. I have an Innova Birdie you are more than welcome to. I never use it.
Note to anyone:
Never leave anything of personal importance in your car when you aren't there.
Justin, I agree that you should hide some stuff in your car (and my wallet was hidden in my glove box), but you really can't clean out your car each day of all the personal stuff. Sometimes, it is just not prudent.
