John,
I like 9--The bunker complex short right of the green is well done, and there is a good bunker short left that guards the best angle in. However, a few others I don't like so much. 1? I guess I didn't get that hole. To me, it seemed like a straightforward, shorter par four to get you into the round. Cutting off the dogleg to gain the shorter route home? That's not really strategy--it's just basic math. Moreover, going left doesn't give you a great angle. That matters if you are a short hitter who can't carry the bunker, but it doesn't matter if you can carry the bunker. Thus, the long hitter has only one option (go left) and the short hitter has only one option (stay right). I guess the green is cool, but I'd need another play to really remember it well.
I remember liking, but not loving, the uphill par three at 13. It's cool, but I feel like I've seen that hole a million times. 17? A long par three with water on one side, which is a decent hole in a vacuum, but very cliche at that stage in the round.
My favorite holes are 15 (forgot this one first time around) and 16. Here, the options are front and center, and the angles are very well done. The fairway bunkers match up perfectly with the ideal angle of attack, and there is plenty of room to allow for an array of options. I just wish the architects could have executed these types of holes on the rest of the golf course.
Ultimately, I think Hiawatha is a decent public course, but it is not nearly as compelling as some other courses in the region (Leatherstocking, Thendara, a constantly improving Seven Oaks, Ravenwood, and, of course, Greystone).
