3 miles from home today I got a flat. Not a big issue as it was the front right tire. Fortunately, on a trike you don't have to remove the wheel to repair the tire. Being so close to home I was hoping to add air and make it back. I was not that lucky. I reached into my bag for my spare tube and tools only to realize I had no tube. Panic set in as I realized I had to patch the tube. I was on the side of a busy road which did not help. I pulled the tube out placed it on the tire hoping to easily find the hole. No such luck. I looked listened and felt to no avail. Fortunately, a few feet away, was a large puddle of water. Placing the tube in the puddle I found the pin hole. I opened the patch kit and was in luck that this old kit still had working glue. I was soon on my way. As soon as I got home I found a spare tube and placed it in my bike bag. I will periodically check the tire pressure on my patched tube. Tomorrow I will buy more spare tubes and another patch kit.
