I probably spend more than most on competitions and most of that is spent travelling to judge.
I know a lot of people who spend more than I could dream of spending on home brewing to hit a ball, drive a small cart after it, and hit it again and in particular to do this in a nice and exclusive location. I think this is silly, but I usually keep that opinion to myself. Everyone needs a hobby, everyone thinks everyone elses hobby is silly or weird (or the way other people in the same hobby participate is silly or weird in this case).
