Paul,
Overall, Huntsville is a very good course..probably a Doak 6 or so
Given the land available, it should have been a great course.
Also, it's a "Challenging" course, which drives high marks from Golf Digest. For instance, they also rank Glenmaura National quite high in the state and that's really not a very good course at all.
But, rather than pick on GD, I think I'd add that there are quite a number of very good holes on the front nine, and the back starts rather promisingly. Unfortunately, the routing takes us places we can't get back from smoothly, and the rest is sort of a disheveled, ledged mess.
