a person can treat anything as a type of religion, basically whatever someone puts above all other things in thier life is thier religion - it's what someone chooses as thier God - thus all the biblical warnings about idolotry, that's not just talking about a statue a person bows to.
On a lighter note - if surfing can be viewed as a religion - I want to open a surf shop and not pay taxes.
I found reading that article was interesting. I found it interesting because it's something we all have in common. Maybee it could be spiritual, enlighting or whatever...but surfing doesn't suggest that there is a person like Buda, Jesus or Rasta. I think the article hints at the fact that with surfing's potentential to globalize, become greener, change your mood by catching one wave is something incredible. A religion is something organzied. Surfing is exactly not. That is why we love it. We don't sit in a box, or read one book, and we all truley fear it. It's oranges and apples i guess. I think acient polynesians used surfing as part of their spiritual practices. I use surfing as my own selfish fetish.
