Whistling Straits - my new favorite course. unbelievable. the 18th hole is just a breathtaking hole, even though I doubled it. 10/10
The Irish - If it wasn't for the Straits, this course would get more props. really, really good. not the views you get on the Straits, but lots of fun, and not too hard to walk. 8/10
Blackwolf River Course - replaces Waterville in Ireland as the hardest course I've ever played. Waist high grass if you get off the fairway, just hit another. A fantastic course though, uses the Sheboygan river really well, and the best greens we played all week. 9/10
Blackwolf Meadow Valley - Same as above, the red-headed stepchild to the River Course, but really solid in its own right. would recommend. 7.5/10
Erin Hills - the toughest walk I've ever encountered. Absolutely beautiful course with amazing bunkering. no water at all. The pros are going to love it in 2017. 18th hole plays 660, can play over 700. Rolling hills among a field of tall, yellow grass. 9.5/10.
I'd put this trip right up there with Bandon Dunes, maybe even a little better. Not a bad course in the package. And easier to get to. The American Club is an awesome hotel, although a little pricey. If I do it again, I might stay at Erin Hills. All the caddies were great.
