My wife once worked at a country club that had the Senior Open. (Not in Nebraska). I had certain golf privileges because I was married to an employee. Well, for about a year, they left the course set up like they did for the Open.
That was awesome. Even though it was the Senior Open, those guys play on courses that are WAAAYYYY different than what the normal golfer plays.
The courses that the "pros" play are ridiculously tough.
I always find it funny when a guy is a scratch golfer and thinks that he can "could probably make it on the tour". The pros are playing crazy hard courses with high rough, fast greens, and a ton of pressure. I heard that Tiger Woods handicap is currently a +5 or +6. That's with him playing "crappy" golf on tour. When Tiger was kicking a$$ all over the place in the early 2000's, his handicap was around a +10.
Long-story short, the guys on the tour are way better than the best golfers at the local muni or country club on a Saturday morning.
