Dear Geoff - having just returned from Corowa I missed this discussion when it started. The support and sympathy you have received is amazing. Just to make you feel better we also encountered an ice problem on our return home.
We had to defrost our refrigerator.
And take no notice of Keith's barbs, (I just spent several days with him around), you can't help living in the land of the polar bears. Chin up, us Aussies will keep sending you warm messages.
Bob
