Yes, there is a great difference between West and East. Back while I was in undergrad (also about 10 years ago) there at UM-D, the beginnings of the shift were evident in East... West, I think, hasn't changed much at all.
Hahahaha. We may very well have met. As I was back then, I would prefer to think we didn't.
I just read a piece on Edsel Ford (where I graduated) and there are quite a few arabs there now but my dad's neighborhood doesn't reflect that at all yet.
