That was my day yesterday. I was already to ride to the office until I found the rear tire had lost about 40 pounds of air pressure, so I drove instead. But I commuted to the credit union after work, and had a nice ride there and back. I scared some critter on the way back. I didn't see what it was, but heard a big splash and same some big ripples in the creek I was riding by shortly after I rode past whatever it was.
