Question for the Southerners!

[WVU alpha phi]

I really want to move to Savannah next fall after I graduate. I've only been there once, three years ago, but I absolutely fell in love with it. I have one concern though and this is where I'm hoping the southern GCers can help me out. I've been told by a couple different people that in the south, you generally aren't "accepted" unless you come from A LOT of money or unless you've grown up there your whole life. My family is by no means poor, but I wouldn't describe us as very wealthy. I've never lived anywhere by Maryland, excluding my college years at West Virginia University and I have no ties to anywhere in the south. I've also been told Savannah is a pretty wealthy area and that these "rules" would definitely apply there. But I'm wondering since I'll only be 21, I'm not moving down there with a family or anything, more of as a "young professional", will I really find this to be very true? If anyone can shed some light on this, I'd really appreciate it!
