Ok so I have never golfed. I've been bowling for about 11 years now and have an avg in the 210-215 range. But from the posts I read through, which I didn't read all of them, I got that no one brought up the fact that true, any one could go take bowling lessons for a few months and be shooting 220's.... on a house patter. Because today that's how centers set up the shot, so anyone that throws the ball out with some hook can get the ball back to the pocket, or if you tug the ball 10 boards it will most likely hold. And they do this so they get more people in there bowling. But you take that person that shoots 220's on that house pattern, put them on a sport shot and they'd be lucky to roll in the 150's.
So yes, just about anyone could bowl a game in the 200's on a walled pattern, probably just as easily as your once a month golfer could shoot under par at their local course. But if you go to a course with more hazards, more slopes around the holes and all in all just a more challenging course, I am sure that person that shoots par on the easy course would have a long day. Just as your average league bowler would on a sport shot.
But then again, I feel like golf and bowling are about as similar as football and basketball. They take different skills to master.
