I used to belong to the Dye Course at Stonebridge Ranch and they added mats there and at The Ranch course. Of course they said they were only to be used due to inclement weather but that turned out to be bogus. Before joining there, I was a member at Eldorado Country Club and they, too, added mats and last I heard you could only hit off grass on weekends. I think there is one day a week, I don't recall if is Tuesday or Thursday, where mats are used at Westridge. I don't know what good mats cost but I've never felt that hitting irons off them is very good for your clubs no matter how good the mat.
