cue my annual, I had 2 flats with some 2nd hand Marathon Winters, in the winter, in the woods, close to dusk, due to a broken wire bead. didn't realize it 'till the 2nd flat. out of tubes, used my last Co2 cartridge & it was gonna get dark soon ... covered the wire with a band aide & bit of electrical tape. it was holding but wasn't sure if it would really hold for the 4 miles back to my car. so, since ppl were leaving the state park, I opted to play it safe & hitch a ride w one of the last fisherman I could find ... survive to ride another day, right?
