Hey Brock,
A couple comments...
1) Otter Creek is no doubt the course you refer to in Columbus. You ABSOLUTELY cannot go wrong there. Try to play the middle and the west nines. These two make up the original championship course which has hosted all sorts of tournaments. But, the other nine is not bad either.
2) You must be a real go-getter. Kind of early in the year to go to Wiscy. Best of luck on that. I looked at the website and the course does look great. I have had the pleasure to play a great many Nicklaus courses and they are all pretty tough but they are pretty much all spectacular. (Desert Highlands, 3 of the Desert Mountain courses, Sycamore Hills in Ft Wayne IN, Pawleys Plantation in Myrtle Beach, and others)
Looks like you could make a great (and very expensive) extended trip to that Wisconsin area.
Best wishes to you and Matt!
