I've travelled a decent bit in California - loved the place. I've met a lot of Californians outside and inside of the state - the guys are usually cool and up for a laugh.
I can honestly say, with my hand on my heart, I have never met a Californian girl that I liked. Never. Not one. Found attractive? Yeah definitely. But liked as a person? No.
And I can say the same for Australians, too. The blokes are usually a good crack, the girls, I just cannot 'take to'.
I have a feeling that it's to do with the place they're from - both Cali and Australia are sunny, lots of beaches, awesome sea....in other words, your stereotypical 'desirable place to live'. It's as though the girls from those places grow up with the mentality of 'everyone would love to live here, I'm from here, therefore everyone must want to fuck me'.
9/10 the girls from Cali and Australia just give off a certain vibe when you're talking to them, regardless of what you're talking to them about....hard to put into words, but something like "yeah whatever, don't even bother trying, I get hit on all the time so don't waste your time" if it was body language and tone of voice alone, if that makes sense.
