Fest, back in the day we surfed in the AM and hit the slopes in the afternoon for night skiing. Every couple of years I break out the surfboard and head down there to remind how heavy, slow and skill-less I've become.
With the boat, I guess a surf, wake and snow day is conceivable. Surf's about 30 minutes to the SW, Elsinore's 30 minutes to the SE, and Mountain High is an hour to the N. Night riding opens at 4pm, goes until 10pm. Mt. High is no winter wonderland, but it's snow, ya know?
