Even at our age (north of 65) we seem to bounce back. It was the uncertainty of the flight doing my head in. My husband is a Cook Islander / Aussie citizen so he actually fit right in, he grew up like that.
Birding adventures still await, road trip to Kangaroo Island, Tassie, Gluepot, Great Ocean Road, NSW, Lake Cargelligo in October. And NZ South Island early next year. Relatively tame compared to last week!
