Of notable course, probably Oklahoma City Golf & Country Club the first time I went to Oklahoma to do Maxwell research. I had not heard anything about it really, knew only a little history at the time, and their website was minimal at best. Ironically I had high expectations for the other big course in OKC, Twin Hills. Both were great courses but OKCGCC blew me away. I was not expecting to find what I found there.
In Indiana probably the one that really threw me for a loop was Coyote Crossing. I had heard good things about it, but nothing that made me think it was anything special. I played really well that day and it was gorgeous in the morning, but I was amazed at how subtle the use of the ground was throughout the course and how the course felt just laid out over it. One of the top 10 publics in the state in my mind easily. Probably to contrast that was my first visit to the Kampen course at Purdue in the afternoon and how disappointed I was in that visit.
Good call on Maxwelton in Syracuse, IN. It is a great hidden gem, not many of those these days on here, that often gets overlooked because people stop in South Bend or the Fort Wayne area and don't go in between. My uncle lives near the course and he loves it. I've only seen it once but liked it a lot. The greens remind me a lot of another course near Seymour called St. Annes. Great green complexes but not much else.
