So... if turf is everyone's problem, what's stopping someone from making "box" greens much like they make sod for lawns? I could see paying an "membership" fee and get the privelage to hit off grass year round or at least through the winter.
By box greens, I mean tee boxes that are maybe 8x8 that can be moved and replaced by other "boxes" with grass that have real grass in them. Each night you could toss down some new greens, to keep them warm, you could have a "sun room" towards the top of the indoor complex and let the sun beat down on it and you can water it indoors and what not. The grass would never know the difference as long as you could simulate a close atmosphere, I wouldn't think it would be all that hard to be honest.
You could use turf for the greens but that generally isn't a big deal since we are all carpet putters anyways.
Maybe I am just out of my mind.
