the rain is about to start. the beginning of a new season. the reality of a new wardrobe. the changing of summer time patterns.
when you surf, it's widely known that you don't go in the water right after the first rain. all of the gunk and stuff from the humans and cars and everything else is run into the ocean from the rain...and therefore the ocean isn't a fun, healthy place to swim in the days following. it's a big shower if you will....for the earth....or at least our little section of it. to wipe away all that once was and start again.
so if you're in northern california....dust off your umbrella. pull out your rain coat. change your wiper blades. a storm is coming. you'll need protection.
