I believe Tiger is credited with opening up golf to a much larger young audience then golf previously got.
That brings in some knuckleheads for sure, but Golf sure seems to have surged in popularity (or maybe I didn't pay attention before).
watching the Genesis invitational inspired me to go to a driving range near me that is open year round (went on Saturday) and it was packed! it was already 3:30 and was getting a might chilly, but every bay in the two level "mats" area were full and there was 20+ people hitting off the grass. every "marked" area was used and people were just hitting from anywhere open.
(and I was horrid... OMG, I suck and golf... why do I even try...
actually salvaged some wedge shots, but I couldn't hit driver for $hit and - of course - the guy next to me was hitting BOMBS.
