To those who live in Cali, I'm moving there after I graduate from college in May, sometime between June-September, and I don't know a single person out there

And I'm really nervous to make such a huge cross country move, but I'm debating between a few places to live, could you give me some advice on locale, or just any helpful things about Cali? Either pm or on here, it's going to be nerve wracking not knowing anyone when I first move there.
