Got back from a ride and rolled my bike into the garage. I was in the process of taking off my helmet, gloves, etc. when I noticed that the tire was noticeably flatter than normal. When I checked, I found a small staple loosely protruding from the tire. Not a big industrial staple but just a little tiny staple from an office-type stapler. I had ridden 35 trouble-free miles only to get a flat tire in my garage after I got off my bike.
