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.
