Whoops - sorry everyone. Of course I know about your grid iron and now realise I should have looked up the atlas before showing my ignorance. Thanks for the explanations.

I'm trying to make myself feel better by telling myself that not many of you would have heard of Aussie Rules or Rugby League!

Tickets: I know you have no way of knowing that my Mum gave me a boy's name but I'm really a girl (that's stretching the imagination a bit these days). I will be around your area in September but won't be able to take up your kind offer as my son and I will be on the Navigator sailing from New York to Montreal. Can't wait!
