It doens't seem like York, PA is a big city.Sounds like their are some spoiled brats there.But I would think that not being such a large city their would be more girls not so materialistic...that want their Gucci and only like guys just cause of what they drive and other stupid things like that.
You'll meet that right girl even if its not in York.Unfortunetly not all girls have totally matured at 21 or 23 so whatever age she may be just make sure you have the right girl.Sometimes girls flaws may not be so obvious

.
If your at a hot/trendy place then you know what type of people you will meet.If you go out with your friends to a not so high class atmosphere the less brats that are going to be there you see.
If these girls are just straight out snoobish and bi*chy then just avoid that, but you know some girls are real nice but come off kinda I'm too good for you, but sometimes its just a way as not to seem so easy and approachable.
