Funny seeing State College referred to as a metro on HN :)
I think one difference is that rural PA and Kentucky have a lot of positive similarities, both being in greater Appalachia. Not as clearly so with CB.
"Metro" may not be merited, but "local area that doesn't feel like Kentucky" is way more characters. ;)
