My perspective is as follows: I woke up this morning at 6 am and rode my mountain bike in the snow for over an hour...it was a decent workout. How many guys wake up early for their tee time and say "Honey, I'm going to go work out..."
Athlete= MMA fighter, basketball player, hockey player, football player, etc.
Gamer= Golfer, baseball player, curler, poker player.
The best use I've ever had for golf courses has been as collegiate cross country race courses...otherwise they are just a waste of space.
