I thought of another time. And this one I only take half credit. Par five, second shot, 280 out. I decide to hit a 5 iron which should leave me 100 - 115 out. The two carts of the group in front are at the green so I take a couple practice swings, line up, and hit. It starts a little right and is fading right, but I'm sure it'll be ok, only into the rough. That's when I see a cart pretty much in line with my ball. It lands maybe 15 yards from them and the 'FORE' was yelled about the same time it landed.
One of the guys, for some reason had driven backward was playing a ball, I don't recall if all four had hit and then drove to the green, I had just looked and they were all parked greenside. He waved his arms at me, he was upset. I dropped my partner at his ball and drove to them to say sorry but they didn't wait. They saw me coming but took off towards the green. This was on 18 and they were already gone to the lot when we wrapped up. I felt bad, but I still think it wasn't totally my fault.
