Started out today on my usual ride, the first truly nice Spring day we have had. The road debris of winter has not been cleared and after a mile or so I noticed some sounds coming from the tires. I stopped and carefully brushed away some particles of sand and continued on. A few miles later I noticed the unmistakable feeling of a flat in the rear tire. Picked a nice spot off the road and began the task of fixing it. Called my wife to alert her that I might need a ride but did not think it would be necessary. Sure enough, after careful inspection I discovered a tiny pin point of metal that had pierced the tire and tube.
It is pleasant to relate that not less than four people, cyclists, a motorist and a homeowner, offered to help.
Knowing that I may take long trips and not expecting my wife to retrieve me I always carry a spare tube and the necessary tools and pump to fix a flat. Obviously, it is time for new tires and I am pleased to have had such a gentle warning.
