The course is definitely unique. It's the only Jim Engh I have played, and it is unlike anything else I've come across...Jim's courses seem to be a very artistic take on golf architecture (as I'm sure has been discussed ad nauseum on here). Some people love it, some people hate it.
It is a very severe course: It has a high slope which equates to death if you're not on with the driver (which unfortunately I was not when I played and got eaten alive; I think it was my highest round of the summer).
As for the 18th hole:
The landing area on the drive is not to small as Chris had mentioned. This is because the effective landing area spans from the left fairway island, down across the rough and cart path that splits them, and includes the right landing zone (see pic below). When I tried to play to the left fairway, I over-cooked a fade (ok...I sliced it) and my ball ended landing on the rough between the fairways and kicking down to the lower fairway.
The issue with the hole comes on the third shot of players that have taken the long route to the hole. If you do not get to the very end of the fairway (probably the last 30-50 yds, which can be a long shot if you're not long off the tee), you have trouble with the three or four tall trees acting as multiple sets of goal posts between you and the hole. Depending on where the trees are in relation to your line of play, you may or may not have a angle into the green (which plays severly uphill from the second shot landing zone). I ended up having to punch a gap wedge between two trees and up onto the green. It was a fun shot, but it isn't for everyone...
It's definitely an interesting hole...
