I don't "get" competitive fly fishing.
I don't either. Actually, I don't "get" any kind of competitive fishing. Fishing isn't a sport, it's a pastime, a hobby, a diversion. Competing at it lowers a wonderfully relaxing activity to the level of all human greed, IMO. I don't even care to fish with people who count fish, like numbers are the ultimate goal.
People who have to compete at fishing just don't "get" its purpose.
