Last flat I got happened this spring a few days before the weekend I'd planned on switching the 26x1.95 Town and Countries I use at the beginning and end of the riding season. I had 2 CO2 cartridges, an inflator, a minipump, a spare tube and a patch kit with me giving me many choices on how to deal with the flat. Instead of fixing it then and there and then changing it again over the weekend when I put the 26x1.5 slicks I usually use I opted to put on the jacket I carry in case I have to stop to make a repair before walking home. I got half way home when I got so hot I had to stop and take the jacket off. I guess you can be overprepared.
