1) Ballyhack - One of the best overall experiences I've had. The atmosphere, the breath-taking vistas, the variety of challenges - I could go on for hours about this course. I think this deserves to be on the "Top 5 RANKED Courses" I want to get back to, but no matter.
2) Leatherstocking - My introduction to Devereux Emmet. A pleasant surprise - I was smitten by the time I had reached the 3rd tee. I know when it's special when I talk about "feeling" a course, rather than "playing" it.
3) Bethpage (Red) - Falls victim to being built next to the Black, but I'd give the Red's 1st and 18th holes the nod over its Black counterparts. Also, if I'm there, there's a good chance my planned "Bethpage Tour" trip has been scheduled.
4) Tobacco Road - Love it or Hate it - you're certainly not bored. Each time I play I find something new, whether it be a hidden challenge or yet another Love It / Hate It characteristic.
5) Coudersport Golf Club - Quirky little course in Northwest Pennsylvania that is as fun as any I have played. Drivable Par Fours and reachable Par Fives, all with significant potential penalties. Throw in mountainside elevation changes and one of the coziest 19th holes, and I'm appalled at myself for not making the 100 minute drive happen in several years.
