Hello Nemo!

View of Bridge and Opera House

I'm sitting by the window of our flat in Pott's Point with the view you see in the picture above. (Except its morning now). We are starting to get past the jet lag that comes from being 15 hours ahead of home base with the help of a couple of …

Slow Down You're Movin too Fast

Grinnell Lake and Glcier
