Cruising down a good hill I felt a sharp jolt; must have been a road defect. Front tire went flat. Pinch flat?
After 4 years (10,000 miles) am suddenly cursed with flats. Decided to carry two tube spares so I don't have to curtail my trips. Fortunately, it was right near the Spurwink River bridge and a nice pier/outlook that offered a good place to change tubes. Rear wheel fit nicely into the rail uprights like a bike rack. Beautiful view of the nature preserve and enough breeze to keep away the mosquitoes. Front wheel, easier to change. Could not understand why my computer sensor was not working until I saw that I had installed the wheel with the quick release on the wrong side. Took me 20 minutes or less. New hard case tires too.
