At about 24 years old (7 years ago), my brother and I would go out to the range and try to SMACK the living hell out of the golf ball to see who can hit it further. Thinking back, the ball probably went no further than 180 yards.
Distance competition turned into accuracy competitions, then into chipping and putting competitions (yes we are quite competitive).
Soon after, we took what we learned onto the golf course. Till this day we still try to up one another playing a round almost every weekend w/ most ending w/ the last hole deciding the victor.
