The 4 courses you should play are Haikey Creek, Hunter, McClure, and Dovilio. I like Hunter and Dovilio the best, but admittedly I haven't played Haikey since like 1991, and McClure is also decent. None of the courses are real difficult, but Hunter and Dovilio are the most difficult.
The new Mohawk Park courses will be nice, from what I hear, but I don't know that they are finished just yet.
If you need an ego boost, go to the Birdiedome (aka Riverside Park)
