I agree with a few things for the Cali one, I'm about to go read the Bay Area one to my boo, and see if he thinks its all correct. But the things that I agreed with are listed below:
You're driving on the 101 and see a clear cut definition of where the smog begins and ends
You see purple and gold and the word "Threepeat" on every corner
(not so much anymore, but it was crazy at one point.)
You begin to "lie" to your friends about where you are (i.e. "Yeah I'm like 20 minutes away") - when you know that it'll take you at least an hour to get there).
You mourned for Tupac and not for Biggie
(I was in the 6th grade when he died, and me and my friends were talkin about having a visual)
Getting anywhere from point A to point B, no matter what the distance, takes about "twenty minutes".
You've inadvertently learned Spanish.
In the "winter", you can go to the beach and ski at Big Bear on the same day.
You know what "sigalert", "PCH", and "the five" mean.
If your destination is more than 5 minutes away on foot, you're definitely driving.
(that might just be a personal choice... lol)
Your TV show is interrupted by a police chase.
(or something that has to do with "a breaking news story".)
You can't fall asleep without the lull of a helicopter flying overhead.
(Not that i cant sleep without, but i can definately sleep during it)
You don't stop at a STOP sign, you do a California Roll.

You've ever bought oranges, flowers, cherries or peanuts on a freeway off-ramp.
(I'm sorry hispanics have the best cherries and oranges in the world... and sometimes socks...)
You think that Venice is a beach.
(Its not? lol)
You've started crossing a street and returned to the curb when the DON'T WALK sign started flashing.
(Thats not just in LA, they do it in Boston too

)
Calling your neighbors requires knowing their area code.
You think Johnnny Rocket's is an accurate depiction of a diner.
(Its a classic)
You've been to Disneyland more times than Downtown.
(Welll... maybe I've been to Downtown Disney more that DownTown LA)
When giving directions , you follow up with the phrase: "With/Without traffic."
(Oh wow that is accurate...i do say that)
You know that if you drive two miles in any direction you will find a McDonald's or a Starbucks.
Your cell phone has left a permanant impression on the side of your head.
You never, ever go into the water at the Beach. You barely touch the sand.
(Hell no, that water is hella dirty.)
Everyone you know has 3+ phone numbers. Home, Office, mobile, pager, two-way, voicemail.....
You are awakened in the middle of the night by a moderate ****. Your reply: "That ain't even a 5-pointer" and go back to sleep.
(Another accurate one.. me and my mom are always jokin about that)
You have to yell at your bank teller through a 2 inch thick wall of plexi-glass.
You go to Las Vegas for a weekend getaway and the whole trip cost you $50.
You know what In N Out is and feel bad for all the other states because they don't have any.
(If only Virginia wasnt sleeping on In N Out....i need to go there tomorrow...)
You know that not everyone in Beverly Hills is a millionaire.
You say you live in LA when really you live in a subsection of a subsection of a subsection of southern LA.
(Hahaha... yeah. I live in Altadena, but nobody knows where that is, so i say Pasadena, but if you arent from Cali you dont know where that is, so i just say Los angeles county :? )
Any major movie star is picking out the best portobello mushrooms next to you at the grocers and you don't notice.
(I dont notice them all the time. My friend had to point out to me that Fat Joe just walked pass me while we were in Vegas last weekend)
