I was playing in a golf scramble at Jefferson Hills Golf Course in Rigby Idaho. After one of my playing partners hit a perfect lay up on the 353 yard 14th; I decided to take out the driver and drive over the pump house near the creek that crosses the fairway. I hit the most perfect draw of my life. Right over the right corner of the pump house on the left side of the fairway. One of my playing partners, Dave, and I drove up by the pump house and could not find my drive. We checked by the green and behind it as well. Straight line tee to green is 321 and it is 5000 ft. above sea level. To prevent holding up the group behind us; we elected to play his as a provisional and look for mine when we were clear of the group behind. Walking across the green, we found my marked, Titleist Velocity #11 in the cup.
