Are there no homegrown Californian nutjobs at all, Goody?
I'm not sure where ground central for Australian and NZ whackos might be.
There are various hotspots for freaks, tree huggers, ferals and ageing hippies and so on, but nowhere here that has the same reputation as your fine state for kookiness, fair or not.
Melbourne's cross-culture, cross-gender, cross-everything overwhelming obsession for Australian Rules football is, objectively, pretty fucking screwy, that's for sure.
I imagine there are a few.
But when you consider that 60% of those currently residing in California are from someplace else [mostly snowbound states, Latin/Central America and Asia] the odds are better than even the guy who wrote this want ad isn't a native Californian.
Everyone wants to live here...including the various assortment of dingbats, weirdos and nutburgers.
It's just a wrongheaded image of California.
