Can't stand the bastards. Mid life crisis blokes in Hawaiian shorts and rashies thinking they're surfers.
Most of them have no board control, no concept of snaking and dropping in. With boards and things that big it becomes very dangerous. Don't care if they stay away from me, but can't stand surfing when they're around.
Granted, there are a FEW guys out there that can actually do cool things on these big boards and show respect to other waves riders....but they are rare.
SUPs have replaced boogers as my most hated water people....actually, I reserve that place for kite surfers
