There are three courses in Lawrence
Centennial is the oldest (I think) and is not too long and can have some really tricky shots. It is the course I frequent since I live about 3 minutes away.
Favorite Hole = Either #7 (long downhill hole with a most-of-the-time dry creek in front of the pin) or #13 (shorter version of #7, except you can drive the creek on this one, and if you really fub a drive, you can hit the skaters to your right)
Hardest Hole = #17 at the long position - if you don't drive up the hill far enough, it is another long, blind shot to the basket
Least Favorite Hole = #16 - it is short, it is straight, a really, really, easy deuce, and I always seem to screw it up
There is also a course at Riverfront park. I have played it twice in the dead of summer. I don't really have anything positive to say except for how impressive their mosquito population is. I will probably go at it again in the next week or so while everything is dead, but I would not recommend it during the summer. Others will probably say different.
The third and newest course is at Clinton Park. It would be my favorite if you didn't have to pay $6 - $7 to get into the park, but it is worth it a couple time a month. It has a nice mix of wooded and open shots, and it just a real natural course. Really nice to be away from civilization to play.
