Hunter's Ridge in Princeton, IL. It's a former private club turned public. Lots of elevation change, compression in the forest, decompression in the meadow, subtle internal contours on the tiny, postage stamp greens. My girlfriend's father is a member there. I played as a fill in with his regular foursome and we got around in 3 hours and 45 minutes - only saw one other group on the course. $32 for a challenging round on a beautiful, secluded, well maintained course.
Cedar Crest in Dallas, TX. A Tillinghast design that hosted the 1927 PGA Championship (they remind you at every hole). D.A. Weibring recently did a renovation that includes the use of treated waste water for irrigation. A whole lot of strategy and fun on a city owned course for only $27 on the weekend.
