vertical - I pinned this onto Crackpot CrAzY! (Overboard!) because this is INSANE! Like WOW, the strength, the power, holy SHIT!! I don't have a board yet to put this where I think it deserves to be, mind blowing, yet scary to me cause they kill us, hunt us OR bite into boarders, swimmers by accident thinking they are seals, etc., whichever!! they freak me out! I LOVE SWIMMING & the Water! but guys like this kinda make me....well in a way, what a bummer, in another it's SO COOL!!
