Also - instruction/facilities are pretty irrelevant; it's not like most people will pay for "top" rated instructors or belong to the top country clubs. The real reason why more pros/ junior golfers come out of FL, TX and CA is bc a greater number of parents/children are willing to go all in on golf - even if that means huge sacrifices, including academics. Not just being a 4.0 student at some small obscure town, but really being able to have the same academic foundation to go to a top college and succeed at such institution (you just wouldn't have the time to practice golf as much as it takes to be a top junior and study). Forget all the other social sacrifices. Because you have more "all in" players, you have much better competition locally, which I do believe is a key ingredient to becoming an elite junior golfer. The reality is that you have a better chance of making millions in finance than becoming a professional athlete. If you were to expend similar hours on academics as some of these parents do in golf, you would have an easier road to a top university, followed by a big-bank job, followed by a private equity gig.
I disagree with the theory of 'all-in' parents in TX/FL/CA being the driver for more top golfers coming from these states, in comparison to the Tri-State area.
Set parenting aside for a moment. Being able to play golf 12 months per year...every year...is likely a bigger contributor.
Didn't the recent junior am champion come from MA?
Michael Thorbjornsen (#9 overall JGS) does come from MA, but I believe he attends IMG in FL
