I had a mike austin moment once as well. I usually hit 280ish and on a 400 yrd green i couldn't find my ball, it hit it dead strait. turns out it was 30-40 yrd from the green so i hit it about 360-370, my guess is it hit a sprinkler head or some rock or something. but who knows, maybe I really did have a 515 MA moment happen for me, as you might have too.
