Charlie,
Another fun course is Thendara, which is about an hour and a half drive along Route 28 in the Adirondacks. Thendara has 9 holes designed by Donald Ross, which include some of the wildest greens I've ever seen from him. The back nine is not as good, but it winds through the Adirondack wilderness and features cool land and some strong holes. In September, it was $23 for 18 holes, and the course is one of my favorites in Upstate New York. Oh, and I made a two hour drive from Colgate to see it, so it is well worth the trip.
