I'm 70 years old and use a Callaway ultra lite bag, and carry religiously, I have used push carts pull carts and motorized carts, but to through that bag of sticks over your shoulders and walk a plush green course is the best feeling of accomplishment a golfer can ever have. I say if you haven't tried it you haven't experienced the true joy of golf in the way it was meant to be played. Yes I know it speeds up the play of game but if people would follow rules and be considerate of others that would make a big difference. Now if you have ever experienced playing the old course or most course's over in Scotland were no carts are aloud you know what I'm talking about, that feeling of walking in the footsteps of golfer's before you, from the famous to the not so good, doesn't matter just the feeling's that you are experiencing for the love of golf by doing it the way the game was meant to be played is all that consumes you
