It was last Thursday, folks. Two days ago I utterly failed to put a new bike tire on a bike wheel. I’m 42 years old; I estimate that I’ve been changing bike tires for over 30 years now, and two days ago I failed to get a bike tire onto a bike wheel. I took my wheels, tubes, and tires into my local bike shop to find out if I had somehow managed to buy the wrong size tires (twice), and they got the tire on in under 5 minutes. (Cost me $15.) I was pretty embarrassed.
