My home course is really quirky, in particular because it sits on a pretty severe site on a bluff near the Mississippi River, is bisected by an old ravine, and sits on about 90 acres in the middle of a major metropolitan area. Those responsible for routing the course(s) on the site from 1893 through the 1920's didn't have the benefit (?) or the budget to move around the land on the site.
The course has a number of blind shots, side hill lies, severely sloping greens, and a unique routing (back-to-back par-3's at holes #2 and #3 and back-to-back-back par-5's at #15-#16-#17 as well as a par-3 finishing hole). However, the course is pretty short by today's "championship" standards measuring just short of 6,500 yards from the back tees and the member's tees (where 95% of men play from) measure less than 6,200 yards.
So, if you were a good player looking at the scorecard before a tournament, you would think "there are 5 par-3's, 5 par-5's and only one long par 4 at 460 yards...I'm going to eat this place up alive." However, the different lies, bounces, and unique shots a better player sees really throws them off under a tournament round. In particular if they usually play at a more straightforward golf course. A few years ago, my home course co-hosted the State Mid-Am tournament on a couple of days where the wind was blowing a good 20mph. The average score was over 82.
