Today was a beautiful day for a bike ride. It was a warm, sunny day, so all the fair weather cyclists were out. Half way home I had a double flat. A thorn from some brambles cut all the way through several threads in the tire. My first patch didn’t stick. My rubber cement was bad. It seemed OK when I checked it a few weeks ago. I didn’t notice until I had started to reinflate the tube. It was then that I realized there was a second hole 10 cm away. Fortunately, another cyclist stopped and gave me two patches that stuck to my tube. I was able to keep enough pressure in the tube to ride home. Riding a severely under-inflated tire is an interesting experience. At least my rim wasn’t damaged. It was still a good ride.
