Let me put Martin's complaint another way.
In my round of golf yesterday I hit approximately nine shots that went the general direction and distance I intended. The remaining two dozen full swings either duffed the ball so badly the target's visibility did not matter or else they were wild enough to be potential lost balls (and one of them in fact did result in a lost ball).
I am very glad that each of those nine shot remained within my line of sight until they had stopped rolling. If I'd been playing a course where one or two of them went over a blind ridge, took an unexpected carom and resulted in a lost ball the result would have been a much less enjoyable round.
I know lots of people around here are addicted to thrill of launching shots that they have no way of knowing if they will find. I am not one of them. The odd blind shot here or there is a perfectly OK feature of a golf course but those shots are never, ever my favorite shot on the course. At most its an annoyance to be tolerated.
