Did you head inside?
(BTW a great fun series)
It was a wonderful series. I knew it was filmed at Narrabeen somewhere and on a hill. Have to admit the footage would have been taken from the best "side". But what was really interesting was that Prof?/Dr ?Susan Kurrle who was the lead researcher/instigator for the doco actually won my category yesterday. Local knowledge. I checked out her route this morning - seems she didn't go anywhere near the facility, choosing to stay to the north of the isthmus.
