Nice spring conditions for snowboarding Tweeze. My buddies and I used to ski in shorts and shirtless in the spring at Mammoth. We would hit chair 5 for fast cruising and then one wise guy would challenge us to hot dog the ridges... bad idea. It gets real crusty up there in spring and I went down once and shredded my back to hamburger. You could probably see the skid marks for a month after. I prefer to wear clothes now.
When you get to SD, there are a lot of nice longboard spots around depending on the swell and direction. La Jolla Shores, Calumet, Torrey Pines, Trails to name a few.

It's been a while since I went surfing as my kids ran off with all my boards.

I do miss those days when the only thing to worry about was that next big set coming in.
