Mike in Iowa City here., 55 years young. I've been a member for some time (a year?) but lazily inactive. Right now out of commission with a badly sprained knee from a bike incident about 6 weeks back. Been a barefoot runner as weather permits -- my limit is about +28F -- for about 12 years. Not a great distance runner, maybe 3 miles a day, usually with my good friend Tank, a German Shepherd/Lab mix.
