The only time I ever drive is if I am going out to meet friends at night or if I have to get groceries. I commute on my bike about 150 miles a week. If you do something long enough, you run into a number of improbable events. I have crushed a door like an accordion when someone in a parked car opened it on me while going about 20 miles an hour and escaped with nothing more than a scar on my neck. I have opened a 20 stitch gash on my leg. I have ridden in single degree weather and three digits. I have had flats and blowouts at inopportune times. I have had to run several miles while toting the bike. I have had to ride it for five miles like a scooter when the chain and derailer broke. I had a crazy lady try to run me down, screaming about she was sick of bikers taking up the road. I've had careless drivers almost sideswipe me. Until today though, I had not killed anything besides some insects.
A squirrel jumped under my tire while going about 30 mph down a hill. Surprisingly, this didn't cause me to wipe out. Besides having to hear the unmistakable pop of bone muffled by flesh, I was fine.
