Redanman,
I usually figure on accomodating everyone all the time! Especially on public courses, where by definition, anyone can play, if they can afford the stipulated green fee. .....In purely philospohical terms, would you design a course for someone who would never show up to play (Tiger) or the potential customer who shows up to play every day? Golf courses are a business, and speed of play and customer happiness index must be considered
At a corporate outing course, like Cowboys, it gets tricky. Not only do you have a wide variety of players from scratch to plays once a year, and today's the day on the course at the same time, but they may be playing the course from the same (usually white) tees in a scramble!
It is this type of consideration that minimizes cross hazards to the degree they have been minimized in recent years! Basically, if we could do it, most architects would design a course you could play with a putter, (ie, avoid all cross hazards) and you would pretty well accommodate all levels of play, while sacrificing certain challenges for the best players.
Of course, this is rarely practical, and even occaisional players like a carry hazard, if not overdone. On the other hand, I doubt the cross hazards would really stop Tour Pros, except in front of greens.
