Golf 101: What's a Handicap Index and what's GHIN?

Our Golf 101 series returns for a special episode answering all of our questions about Handicap Indexes and GHIN. A huge thank you to Ainsley Kuppler (Handicap Index: 39.6) and Frances Nee (Handicap Index: 26.5) of the United States Golf Association for breaking it down for us.  Some of the questions we tackle include:  Why should you get one?  What will it add to my golf game?  How is it calculated?  Once I sign up, how do I establish my Handicap Index?  What if I don't keep score on every hole?  Where do I post my scores?  Does my "number" matter?  You can register for a Handicap Index today at usga.org with this link.
