I'm not one for "The Beach" as sold in vacation packages, but I have a great need for the ocean. Growing up, I spent hundreds of hours at the shore, a cold, windy shore, rock climbing, studying tide pools, watching the waves and all the other things a curious kid could get away with. Mountains/hills/forests make me claustrophobic after a few days. I need to be able to look out across the water toward infinity once in a while to recharge my mind.
That being said, spending the day on the sand while scantily clad is a great way to boost your vitamin D level.
