And this is one of the neatest: It's Kev Rohrlach's personal collection, which he made into a museum. He has everything from rocks to rockets, costumes, old steam engines,, and technological oddities like a six-cylinder engine with only 5 moving parts (really!). The museum is between Tanunda and Nuriootpa in South Australia.
This picture shows me, my wife Sandy, and Kev in the museum in 1991.
Very sadly, Kev died in an automobile accident since the first version
of this page. Word is that the museum is being sold off piecemeal
sometime in 2001.
