Well its easy to say a walker is slow when you're in a cart. I walk 99% of the golf i play and ive never had much of a problem keeping up with players in carts or had much tension. But if the course is open, the walker should probably let the riders go if they're moving at a good clip. Depends on the group.
As a kid I had an interest in trying golf, but nobody I knew actually played. It was certainly not something my dad tried to encourage considering the cost.
I went to college, worked away and then came back to my old hometown years later. One of my brother's friends had picked up golf in the mean time. This little scrawny kid I barely remember was now a 6-foot-5, 300-pounder who played golf. He was always looking for someone to go out with, so he got me started at the local par-3 course. I guess I hit something half decent that day and kept coming back for more.
Yes, Big Man can crush the ball. No, Big Man can't count his strokes properly.
You never did answer as to whether or not you were holding up the group behind you. Because, if you weren't, maybe stop and smell the roses a bit. It's a treat to spend 5 hours on Pinehurst #2, not a chore.
