Surfing is sensual. It's a real-time engagement with the forces of nature, which happen to be echoes of the past (which after all, is all a wave really is). Briefly we defy gravity and ride the energy of storms from elsewhere. We are intensely alone as we do it and yet completely swallowed by something larger that enforces a sense of perspective and connectedness to the natural world. It's an experience we yearn to repeat so we go searching for it again and again and we spend years sitting in the water waiting for these radiating lines to come in across the event horizon.

Humour's the pay-off for all that existential horror.

Surfers travelled and opened up and changed. It became more mainstream, less of a cult. And it diversified. On any given day in the water now I'll meet three generations of surfers, male and female, everyone sporting a different craft. I started surfing in the 60s and I can tell you it's infinitely more diverse. It might be more crowded but it's also more interesting.
