I started when I was about 7 or 8. Played off and on through my teens and shot mid 80's to mid 90's, but really spent my time surfing and skateboarding. I thought golf was for old guys.
My first lessons as a kid were from John Anselmo (tiger's first teacher) in Bakersfield, Ca in about '68. He was married to a friend of my mom's. I guess he said I was a natural, according to my folks.
My thoughts on the sport? It's a game, not a sport. I love the competition, but more the mental aspect and the fact you are really playing against the course more than another person.
I wish that I had been a little more interested in it when I was younger, since I've noticed a pattern in my life of enjoying individual athletic activities more than team sports.
Surfing, skateboarding, snowboarding, and hiking have always been at the top of the list of things I most enjoy.
I started getting serious about the game in my early 30s as the surf was getting too crowded, and I finally had good income. I also found the game allowed me to become closer to my Dad and spend some quality time with him after all our contentious years due to my wild and misspent youth.
BTW my current index is 7.8 and I usually shoot between 77-82 pretty consistently. I'm a certified addict now.
