58 miles in the rain last Saturday with a group of five. 6 flats in the group of five. For whatever reason, I did not have a flat. Also, as I reflect on it, a patch kit, glue or glue-less, would have been more or less useless. As soon as the tube came out of the tire, it got wet. One guy, not in our group, allowed as how he had experienced 3 flats in 13 miles. One of the SAG people mentioned that flats are more prevalent in the rain. When queried about this topic, the proprietor of my really local LBS said that he had heard the same thing.
