Hadn't seen this one, thanks.
Some of the in-course OB is there for good reason--the drop-off into the woods is severe you'd need a rope and pickax to climb back up. In other places it's frivolous, but the woods are so thick that looking for your ball--much less playing it--would slow things down even further on a course where place-of-play is already an issue.
Agreed with those mentioning the short course, it's my kids favorite. It's has the feel of a "real" golf course, with 9 very different holes through a corridor where (other than on 4/5) you're isolated from the other holes on either course. Walking only!
