Great Bob. It is so simple when you get enough information. "On the wallaby track" really does make sense.

BTW speaking of wallabies. When I was in Tassie I ran into (figuratively!) a tiny member of the Kangaroo family during a bush walk. I was told the name of it, but I didn't write it down and now I forgot. Do you know what the next step down in size from the wallaby is called there. It was a real little fellow that could think it was hiding under a little fern bush.
