Oh a golf ball can do a fair bit of damage, I've seen it happen once. My last spazz school, a boarding school, got a bunch of us taken out on a golfing outing for a bit of R&R, and I happened to be in the right place at the right time, this girl, joanne, hit a million to one shot, unless she had talent she wasn't letting on about, while one of the staff was a good few hundred yards away in some trees, belted the ball with her driver and managed to hit the guy right in the back of the head, dropped him to the floor. He noticed it alright, probably lucky he didn't end up in hospital.
No permanent harm done though, luckily for him he was pretty far away at the time, all the same, it knocked the stuffing out of him.
Even funnier than the driving range incident, where I fucked up royally, and twatted a ball into the side panels of the stand enclosure, hard as I could, only it didn't go anywhere in the intended direction, and went on to richochet around WAY too damn close for comfort. Bloody luck I didn't get hit then myself.
Ever noticed though, that those who actually take up golf as a hobby/sport seem to often prove a real pack of stuck up, poncing dickholes? There's a place I go to pick mushrooms, and there's a golf course sort of looping round a forest in a vague horseshoe shape, there's a private golf clubhouse there, but the entire area is public right of way, and I've had fucking mental cases threaten to try caving my head in before for going there, not in their way, I make damn sure to keep OUT of the way, after what that chick did in my old spazz school, and still, quite a few of them are abusive, sometimes to the point of threatening violence. It's never once been the dog walkers, never once been the hikers, only the fucking golfers.
