Something about being out in the beach, riding the waves; kind of extreme but relaxing the same time.
I'm not any good at surfing yet, but it seems that surfing can be as extreme or relaxing as you want to make it. It's nice to be out on the water, sitting on your board, just waiting for the next set of waves. Since I'm learning to surf, I try to keep to the smaller crappy waves that the serious surfers don't want. Also, that way I don't have to worry as much about nose diving and toppling over the front of my board. People keep telling me it just takes time to get surfing down.
Thanks for the compliments, guys!
