For me it depends on the time of year. Too early for the beach, so I'll get out and do some steelheading this spring. If you think snowboarding is an expensive, try fly fishing (not to mention bow hunting and bird hunting in the fall). But as Sam said, you have to appease the gear-whore beast that resides within somehow.
Thinking about doing a Gus Macker again this summer, but can never get a group of guys to coordinate on it. Plus, it's been a while and an injury for the snowboard season is something I'm not interested in.
I'm going to hit the weights and workouts even harder this year. Next year it's time to finally get some air bitches!
