I had three flats today. First one knocked front tire off rim, no big deal air it up and go on. Second one on rear, plugged it and off again. Third one was a pain in the butt, other rear tire. I had a tube pull in it a couple of months ago, normally I would take one with a tube to the tire shop, but Labor Day its closed. My helper and I broke it down with two crow bars under a shade tree in the town park where we were mowing. Bad part I had a plug kit I brought a while back and it had some patches in it with, made in Twain glue. So far its holding.
