I've been playing golf for 15+ years and work in the golf industry and still haven't had a legit 9 or 18 hole round HIO until I played a 9 hole round at work with my girlfriend and her Dad! Best part is I hit it well and turned around to let her dad hit next assuming it would be a 3 ft putt or so. He kept watching it and after about 5 seconds or so yelled "IT WENT IN!" I wanted to run to the green to see if it was truly my first. She missed the whole thing. lol
