I am happy to report I got my first flat tire since I started commuting on my bike again. I was sort of dreading it because I am not mechanically inclined and have not changed a flat in years. I had everything I needed in my backpack though and it only took me about 10 minutes to put the new intertube in and I was on my way. Those little bike pumps are not any fun.
My questions is whether it is worth patching intertube that went flat or just to throw it away. I have a couple of spare new tubes.
