X is what I am-blew out my knees 100 years ago ....so I surf by proxy. Just found you thought I'd trip around. I've never heard the term Grey Suits for sharks, which is pretty cool, when I surfed early 1980's. I was too busy trying to get from the pit over the hill without getting busted for cutting school. Never too late to learn what you guys know! Now, 100 years later I still have some seaweed in my brain and it's a good thing!
