If I really need to know if I'm directly over something, I take into
account the wind and my velocity and start dropping golf balls and
watch where they land. Of course, by the time they hit the ground,
I've probably moved a couple hundred feet or so which then requires
more golf balls. It's a never-ending battle.

Seriously?
