Avocados- they have strange large avocados from Florida, you can still find the California Haas avocados but you see the Florida ones in stores more frequently
Seasonings - McCormick and Lawry's no where to be found- lots of weird named seasonings- i miss the brands and labels that I know
Best Foods Mayo is Hellman's Mayo and Dryers Ice Cream is Edy's Ice Cream- the logo's and packaging are the same - the name is just different
Here "summer" is a verb, where are you summering? I summer in the Hampton's. Even karate schools and kids camps advertise come summer here. Back home summer is noun. What did you do over summer is how the west coasters roll.
Here- A 30% chance of rain defines just about any summer day- don't forget the thunderstorms which are perfectly normal when temps are in the 80's
That's all I got for you now, but I'm sure more will come to me later on!
Oh wait... I just thought of one more
In California-people finish thoughts with "ya know?" or "Yea?"
In NY they finish thoughts with "right?"
