I've had it off for years. Gonna go see if it changed. :-)
*Edit-
andyson: I does follow the direction of the wind, on the tee and on the green. Even the shadow is correct. (and the shadow moves as well.)
They sure do. They are nothing like they were when I turned them off. Looks like they did a pretty good job on them, too.
I did notice where what Courteney pointed out about the meter comes into play. LOL. Impressive job but not at the cost of an occasional meter skip. :-D
