JC,
I have always thought that if they could prove that the course or designer knew or should have known that a situation was obviously unsafe, the course was liable to change things.
Someone did a tort seach here a few years ago, and found that there were actually very few golf course lawsuits regarding being struck by a ball. But, I read an article yesterday saying golf was "fertile ground" for lawsuits, mostly as golf courses try to sell to developers and surrounding homeowners want to keep it green.
BTW, the silliest "I was there second" lawsuit I ever heard was in Chicago, where a gentrifying north side neighbor hood sued to have a chocolate factory that had been there since the 1800's stop operating, because of the "noxious odors." I always thought that the smell of warm chocolate was pretty good myself! I would have sued later after gaining about 400 lbs.....
OT, but while I'm on the subject, watching the Dallas Stars the other night, they had to press a rookie goalie into action, who had a shut out going for 59:59 and then lost the game in OT, despite making over 40 saves. After they gave up the last second goal, the announcer, thinking they were off the air for a commercial commented that the goalie ought to sue his teammates for their performance.........
