Well Grouse, I didn't know this. Thanks for the tip. I also have a plug kit like Dave mentioned, but in case of a slice, I may just pack me a tube of super glue in my emergency kit in the truck.
Also, FYI, for those of you who ride the backcountry roads in the winter: I keep a ziplock bag in my truck with wooden matches, 2 emergency candles, an empty soup can (to burn the candles), and a couple granola bars. The candles will keep you warm in your vehicle, the granola bars will fill your belly, and the ziplock bag can be filled with snow and be your "canteen". Placed in your vehicle to melt and provide you with water to keep you hydrated.
