What is the most important item you carry in your bag during a round other than discs
Tournament - Birdie Bag because I live in the South and the humidity is brutal during many summers rounds and dirt does not always work for me.
Casual - Camera! Due to travel, I have been able to capture images not only of courses but landscapes surrounding courses. I actually enjoy the photography aspect of photographing courses more than playing now it seems. BTW, I am the worst photographer of people and really have a difficult time consistently capturing good images of players throwing.
