'I understood how it worked'
well done, bet you bought a t-shirt too!
i've been surfing for over 30 years, my whole life has been shaped by surfing, and i still don't get the entirety of it. on my best day i maybe just glimpse it.
lets face it, you can either ride a board or surf a wave. 99% of the idiots these days who litter the line ups are the former.
