I know that I'm old fashioned, and I did caddy my way through college back in the 60's, but I sure wish more courses had caddy's.  Some of my best rounds, and surely most memorable, were played with a caddy, most notably at Pinehurst #2.  For me while a caddy, I was on a course and watching and learning.  A good caddy knows your game in a few holes and helps you to get your best score with your skills which pays off in a tip for your services.  From a business viewpoint golf carts contribute to profitability more so than caddy's .  I just wish that I had a choice.  What's your opinion, would you walk and use a caddy if available?
