As for your golf bag, you don't need a large tour-sized monstrosity with your name on the side
. I've got one because I play professionally and someone pays me to use their equipment. But you should go the understated route. Especially if you're going to be carrying your bag, go small and get the kind with legs that fold down automatically to support the bag. First, you don't want to be loaded down on a hot day. And second, the last thing you want to do is draw attention to yourself. Blend in. Be one with the environment.
