i'm not trying to be spiteful!
i'm not sure i agree, though, on the raw cost elements. you're acting like anyone can just buy clubs and walk on a golf course and its just like playing putt-putt. aside from the "etiquette" that tends to come with spending time on golf courses. its a little disingenuous to say that someone born to a household on food stamps is as likely as someone in the suburbs to grow up golfing.
off the top of my head: access to lessons, driving range, clubs that fit - knowing someone who can tell if clubs fit - clothes, spikes, tees, balls. come on, pal, thats a little more expensive than twenty bucks. i accept that not everyone is like me, and requires 10 trips to the range before they have the confidence to play a round, but its not as easy as you're making it out to seem.
