I live in puncture weed, goathead country. It's everywhere.

1980 Schwinn Voyager 11.8 - nostalgia - Gatorskin 27x1 1/4
199? Specialized Hardrock - commuter - Crossroads Armadillo 26''
2006 Lemond Sarthe - training, touring - All Condition Armadillo 700 x 25

I had tire liners before I upgraded to Gatorskin/Armadillo and I still use them. I know makes for a heavy tire setup but I hate fixing flats and haven't had one in 3 years.
