When I went to visit some friends in Idaho (the “don’t californicate idaho” bumper sticker is also seen), I mentioned to the store clerk how I went to school at good old BSU (Boise State University.)
Clerk: So where do you live now?
Me: California.
Clerk (after a pause): I’m not like most people. I don’t hate Californians.
I moved to Oregon from California (Santa Cruz)in 1970. I caught a lot of grief because I moved from California, even though I am not a native Californian. I was castigated for “stealing an Oregonian’s job” to which I always asked why my employer found it necessary to advertise his job openings in the San Francisco newspaper.
I was also severely beaten in a bar for daring to suggest that (then) Cassius Clay was exhibiting courage of the highest sort rather than cowardice when he refused induction into the armed forces.
And, in the town where I was living, a touring hippie was thrown in jail for having a bumper sticker that stated “Get your shit together.”
My experience may not be typical and results may very among other participants.

Well, because it’s just not natural! 
Next time I start ranting about my sympathies for the columbine killers or something of the sort, please realize that I’ve been here for 15 goddamn years.
The problem is that the out of staters visit Oregon on days like today. Today, the sky is blue, it’s a cozy 70 some degrees out, Mt Hood is in clear view to the east… a perfect spring day. The ride down 26 to portland must look beautiful right now. Yes, they come on days like today and see the beautiful weather, the nice people, and the glorious foliage and they think this would be a perfect place to live…
…WRONG. Suddenly, like an angry god lashing as his feeble creation, the skies turn to grey, and a torrent of liquid falls from the sky. They retreat into their SUVs and quickly dial their loved ones on their ubiquitous cell phones to wish them their goodbyes. Like lemmings, they rush at breakneck speeds down the highways, oblivious to such concepts as static vs sliding friction or traction… they muck up traffic for the rest of us, they ruin our cozy little lives… and they never think to carry an umbrella. (I have another little place in my heart reserved for Washington drivers… and Idaho… gods I hate Idaho…)
Then again, I was born in Anaheim. My best friend is from SoCal too. I don’t think it’s so much the Californians that are hated, but their lifestyle and attitudes. Though with Intel and Microsoft turning us into the silicon forest… I may just have to try to find somewhere saner to live… Like Maine. Or Rhode Island.
That reminds me. Every time I tell a caller that I’m in Portland, without fail, they say “Beautiful country out there”. That’s how I know they’ve never been here. Not in the winter at least.

“I never meant to hurt you,” you said
And buried yourself in lies instead.
Next time I would rather be slain
Than forced to bear your mercy again
I live in Colorado but am not a native. Native Colorado residents HATE people from California and have the same kind of bumper stickers that have been mentioned, “Don’t Californicate (Add state here)”. I personally don’t care, anyoone is welcomed anywhere. I’m a New Yorker and I know people can’t stand people from there. I’m guessing that most of those people who feel that way have never been there or if they had, they were scared by a bad experience. That’s all I have to say.

Just for the record I was trying to report what I thought were general sentiments in the local populace about Californians, not my own personal sentiments.
Some of my best friends are Californians.
Half the people in Oregon are FROM California. Ironically it’s that half of the population that bitches the loudest about us coming up there and spending money in their economically strapped state.
