Yesterday I had to drive a disabled friend to get some medical treatment in a city that is 150 miles away over the mountains. Long story short, I rented a car at 8:00 A.M. and didn't get back home until 8:00 P.M. Most of that time was spent driving. Today, while walking to meet my wife at her gym, I noticed the top of my right foot/ankle aching from the driving. I guess I'm just not strong enough to be a motorist. Good thing I can cycle the sixty miles I need to travel tomorrow.
