I forgot to close the straps on my Carradice seatbag when leaving work one day and lost my wallet and eyeglasses. That was a very expensive lesson to learn. I noticed the open bag about halfway home and retraced my route, but only found a few scattered cards from my wallet. When I got home, I called my credit card company and someone had already charged $500 worth of electronics equipment at Best Buy. Fortunately, I didn't have to pay for the bogus charges but the new eye glasses cost over $300. Needless to say, I now double check everything before leaving.
