Knowing when you are overflying something

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.


Bowling balls work better:
