My 1974 senior year at Kinnick High School (aka Yo-Hi)
Yo-Hi is short for Yokohama (before 1972) / Yokosuka High School, Japan (unofficial school name).
Kinnick High School is located at Yokosuka U.S. Naval Base, approx 50 miles south of Tokyo, Japan.
That's how I looked in 1974, my senior year at Yo-Hi!!! 
I attended Yo-Hi from January 1971 to my graduation in June 1974.

During my senior year, I participated on the Varsity Basketball Team
and the Cross Country Team.
