way to go Techno! I've become quite proficient at changing flats,,, had 9 in a 3 week period! And 4 of those were AFTER buying a new tire to replace the one that I had 5 of the flats on... AAAACK! I finally gave up and put gatorskins on... I have stopped and helped so many other riders tho, that I feel like roving sag support... I figure what comes around goes around, and someday I'll be helped when I need it!
