Keith Burgess-Jackson, J.D., Ph.D.

I lived in Tucson from August 1983 to August 1988. During that time, I rode my bike thousands of miles, but didn't run a foot (except to catch a Sun Tran bus). One time, for kicks, I pedaled up Mount Lemmon, which tops out at 9,157 feet. Now I see that there's a marathon race up the mountain.
