It's open year round, so when you have a nice weekend in early March you can still play.
It's fairly challenging... most birdies are rare enough here to actually mean something.

A lot of the course is very swampy for much of the year.
Too many blind holes.
The course is usually very windy.
I have a love-hate affair with concrete tee pads, especially on long, swampy courses. I want to wear cleats for play in the fairway and the rough, but cleats don't ride well on the concrete tees.

When originally designed, there were few trees (in fact, they had paper-mache trees and hale bales for obstacles). Now that a bunch of the trees have grown up, the fairways have disappeared (for example, hole 5 has become pure luck... skill is no longer a significant part of this hole. There are similar problems with growth near hole 12 and others over the past 20 years).
I know that everybody else thinks having a bunch of 700+ ft holes is cool, but for me, it's just boring and stupid.
Similarly, when I bring newbies here, they ALWAYS lose a disc... whether in the high grass on the rough (rare) or the deep and blind water hazards near holes 6 and 9 (common). It is also too easy to lose a disc on hole 15 since the trees have grown, because the hole is now blind.
I don't really care for the artificial bunkers, either... they make me conscious of how artificial the holes are. As someone who's been playing since before Steady Ed's marketing of the pole-hole, I like courses that are more natural.
