These responses have been hysterical! I particularly like the idea of freezing it in a metal can so you can't microwave it!
That sounds like the voice of personal experience!
Last night, we had a 'plasectomy,' cutting up all but the one emergency card. That one simply went into a bag in our bill file for emergencies. Like Rush said, just like AA meetings won't keep you from drinking, hiding the card won't keep you from using it if you decide to do that.
Also, my planned storage place was pretty hard to get to, and my wife had a good point that if something happened to me, and the emergency required her to use the card, she wouldn't be able to get to it.
But most importantly, we're done with credit cards. This one is just a security blanket for major emergencies, until we get to where we can manage them on our own.
Also, I have to refinance my house next year to get out of my bankruptcy interest rates, and some unused credit on my history helps my score. (My score has already gone up a few points just by having some unused credit, believe it or not!)
Thanks to everyone for your ideas!
