Morality and religion are not mutually exclusive ideas however they aren't always a package deal. I don't know if i would put surfing under a pagan classification. It transcends a strict connection to nature. Most pagan religions are connected to nature in return for something.(good harvest..etc) Surfing dictates morality not because a surfer wishes to receive something in return, but because he/she knows it is what is right (or wrong.) To think otherwise would be hedonistic.
i think you just contradicted yourself. if surfing becomes the center of your life or way of life, isn't that in itself hedonistic?? I mean, we surf, because we get pleasure from surfing - correct? Some would opt out of sex or blow off many other things in order to not miss a good day of surf.
