I seem to remember that one of our members (one of the Steves I think) used to be a Hula Hoop champion.
Anyway I saw this article in the Guardian & it made me think about that. It's funny how such simple items as hula hoops & frisbys have affected our culture as almost every household with kids has got one or other or both at home somewhere.....
