How to make a decoy wallet

I found an interesting article on How To of the Day that might be useful to Memphians:  How to make a decoy wallet.  It protects you from having to cancel all your credit cards and get new IDs if you get mugged.  Basically, you get a cheap wallet and dress it up with a minimal amount of cash (maybe a 10 or 20 and a few 1s), an old photo ID, a couple of expired credit cards, and whatever else you can find with your name on it that you don’t need.  Then, in the event you get mugged, you hand the robbers the decoy.  By the time they figure out that you’ve handed them a few bucks and a bunch of useless cards, you’ll be long gone and safe.
