So, it’s beautiful outside I tell myself. In fact, it’s a perfect day to hit the bike trail. What the hell, huh? So, I get my shorts on and tie my hair back with four binders. I pump up the tires, fill the water bottle, and head north on the trail. I’m listening to Beethoven’s 1st Symphony when I suddenly hear a hiss and feel the rear tire start to ride rough. Yup, flat. And I am 2.5 miles or more down the road.
