odd practice

dangerous but i believe effecting practice

me and my dad was out in the pasture hitting PWs at each other trying to get it closest to one another, scary but fun

i believe it really helped with our aiming and alignment

Try using some "birdieballs". Just as good, and much, much safer.

When Tiger Woods was a boy, his late father would stand in front of him and get Tiger to pitch balls over his head. Fortunately for his dad, Tiger turned out to be a pretty decent player.

Hi Doogkie,
That sounds like rather dangerous fun, the sort of game my son will also enjoy. But we will both wear helmets if he wants to try it.

i got some birdie balls, but there is nothing like hitting a real ball, not to mention at each other

Annika Sörenstam often has her caddie SITTING on the driving range with a baseball glove as she hits balls at him.

If he can't catch the ball, it's a bad shot. It's really disturbing to watch (mostly because she hits him easily inside some 130 yards).
