We were waiting on a group ahead of us last weekend and I apologized to the group behind us that we weren't making more progress. They said it was OK, they didn't have to be anywhere.
American golfers spend far too long waiting around to hit shots these days. While there are a few die-hards who don't have to be anywhere soon, slow play is an inconvenience for just about everyone.
What are we going to do about it? I believe that if we as individuals start to do what we can we'll find that others pick up what we're doing. Don't be afraid to gently (or not so gently if necessary) teach your foursome how to play an efficient round of golf. So, what will make a difference?
