Some were pretty ordinary, but most were really interesting.
One of the strangest were two couples I was sandwiched in between in a really packed caravan park in Alice Springs.
I joined them for a late afternoon chat but was gob smacked when all they spoke about was how much money they had accumulated in their working life. It was like that Monty Python sketch about living in a hole in the ground. Each was trying to outdo the other. I kept my mouth shut.
By far the most interesting was in a roadhouse park where 2 fairly eccentric fellows about my age set up a tent next to me. When I say two, one did ALL the work, and the other just watched.
The tent was the the most ridiculous tent ever. It looked like it was bought in Kmart in the children's toy section. It was shiny red and yellow and looked big enough for two eight year olds.
How they fitted in I don't know.
I got talking to them because neither of their mobile phones worked and showed SOS only. They were pressing buttons randomly, and trying to send texts with no result. They were obviously totally bamboozled by technology.
After I got talking to them, it turned out they were both professors of Earth and Paleo Climate Science at ANU university in Canberra, and one of them, the one who stood around had discovered the worlds largest meteor impact site in Australia.
I looked him up on Google, and he is actually quite famous.
For some reason we got on quite well, and he was busy explaining the theory of meteor impact sites.
They were on their way to Wolf Creek, and then the Pilbara.
In fact he invited me to visit him next time I visited Canberra.
The other interesting couple I met while whale watching, was this fellow who while sitting around the campfire, pulled out a selection of home brew including beers, gin, and whiskey. He had been an industrial chemist during his working life, and now usd his knowledge to make all the experimental drinks.
In spite of not going to plan, it's been a great trip, and now it's homeward bound
