Why is it crazy to carry cash? I'm in my own town, shopping during the daytime (usually), not lurking around some alleyway at midnight. I'm also not afraid to park my car in a lot for fear it "might" be stolen, even with packages in the trunk. But that's because I know my town and which areas are high crime, and don't go there.

If I'm traveling it's a different story. Then I'll take my debit card and a credit card. I'm not totally anti-card you know....they do have a useful purpose.
