Play golf both left-handed and right-handed. An homage to Howard Wilson Hartman, my father, a great athlete. My best, in best shot is 74. I'm a bogey golfer, right handed. Hit right-handed from the whites, left-handed from the senior tees. Take the best shot, hit both right-handed and left-handed again. Continue.
I've broken 100 on three different courses, playing 9 holes left-handed and 9 right-handed. Triple bogey max, left-handed.

Maybe someday George Washington Hartman and Descendants Hardware can sponsor a world championship in Ambidextrous Golf, though there is much to be learned by a search of the web.
