Twice this year, 1st was the end of a 60 mile ride in July with temps in the mid 90s and high humidty, I flatted about 4 miles from home and just decided to call the wife for a ride instead of baking in the sun fixing it. The 2nd was after a flat in mid September at 7:15PM and when I changed the tube, the seals blew out of the head for the CO2. Since I was 10 miles from home with not much day light left, I just made the call (stopped and got a Morph G pump on the way home).
