Yesterday the mud at our course seemed to be just the right consistency to stick to golf balls in quite big lumps. I hit some shots from the rough or semi-rough that had some very strange trajectories, something like an out of control November 5th rocket. On one occasion I didn't bother to pick clean and place under Winter rules on the fairway, because the ball looked clean and was lying nicely, but got the same problem. I guess that the ball either had a lump of mud underneath that I couldn't see, or picked up some mud as I hit it. Does anybody know a way of predicting the flight and distance of a mud ball? They all seemed to lose distance btw.
