People have to realize that a boat can go under even if the flow isn't way up. I think all of us that own boats at some point have either had a close call, have seen a close call or have seen what happened on the Cowlitz. I wear an inflatable vest even though I can swim well but I realize that even if you are good swimmer cold water shock can turn into a stroke or heart attack. The life vest can keep you floating above water but it won’t matter if you’re dead.
