Going back to the OP's first post (not sure where to post this) what is a float? I've heard it before by Aussies especially but living in America my whole life, I have no idea what it is. Lol. I first assumed it was water of some sort, like the shore/waves or something, now I'm thinking more along the lines of a horse trailer.
Sorry that was totally random, but I've been curious about it for awhile.
