I've never played there but I do have maybe 15 loops under my belt at Butler.
The course itself sits directly in the middle of a very busy commercial area. The course is just south of a huge mall, roads and highways surround the golf course. The entrance of the club is shared with a local public muni. Driving down the road, a half mile from the course, you would never guess there is a great golf course nearby.
As mentioned, the course is incredibly demanding. You have many odd or weird angles off the tees and into greens. The par 5's are tough to beat up becasue they tend to dogleg one way or the other and are hard to get at in two. The course has many mature trees, but there are some open areas as well. There isn't a huge amount of elevation change throughout the course, but it isn't dead flat either. I know the course went through some renovations some years back. I haven't see the place since those renovations.
I think each year Butler had the highest scoreing average of any tournament on tour when the Western Open was held there. I know some of the back tees were not even used for the Western. The course is very, very hard. The course just never lets you get comfortable as a golfer. You always seem just a little off balance.
With all that said, I think Butler offers a fantastic golfing experience and if you can gain access, by all means, tee it up.
