I had today off. Bride was working, no comitments except yard work so I donned my riding clothes, loaded up with hydration, cell phone etc. and headed out about 7:30. Beautiful riding for the first 17 miles. Then the brand new front tire went flat. No big as I have attended the flat tire class. Got out my trusty repair kit including tube, leavers, CO2 inflator. With tire on I was hurting my arm slapping myself on the back for a job well done. Ten miles later I hear a slight tick comming from the front. Looking I see a small bulge forming on the side wall! A hundred yards ahead is a turn lane so I opt for the additional space to pull over. Never made it before it exploded. My blackberry decided at that momen to lock up. I walked the bike 9 miles in my socks (that wore through at a mile) to the local Walmart where I bought the wrong size tube (all they had), water, socks. Installed tube, used my last CO2, then rode back, slow. Now whining about the blisters on my feet.
