I have always liked this feature. After seeing it again at White Bear, I did it at the Quarry.
When I worked at Glencoe GC in Illinois, they had the back of some par 3 tees converted to putting greens so golfers could do something while waiting to play.
It seems kind of old timey, but on the first tee, really convenient, too. I saw it mentioned on another thread and wonder if any of you have examples.
