Kalen, I bet the 13th at Qualchan is the most hated hole in the entire Northwest. I've talked to people in the area that won't play Qualchan because of that hole alone. I agree, it isn't a great hole but I don't seem to despise it near as much as everyone else. It offers a quirky way to drive the green if you're willing to take your chances at driving it through the trees on the left. The biggest complaint I have with that hole is hole virtually every tee shot is going to find it's way to the same landing zone at the bottom of that hill. It takes a lot of the skill out of the tee shot and beats the heck out of the ground where everyone is taking divots.
#10 I actually don't mind at all. I like the option of driving it over the trees on the right towards the green if you want to be risky (I've only pulled that off once in about 5 tries) and I think the greensite is one of the better challenges on the course with the deeper, skinnier green with the horseshoe bunker on the left and the terrain sloping down to the right.
#18 I agree is tough for seniors and ladies to reach the regular green which is exactly why they put the 2nd green short of the creek to play to, but for other players it is an exciting approach shot up the hill, over a creek, to a back-to-front sloping green. I like it.
