I had two dorm buddies at ND who were from NJ. One lived in Dover and the other in Elizabeth. I went back east with them during a school break and visited their homes. Though not that far from each other, the two cities could not have been more different. As I recall Dover had lots of green, rolling hills and expensive homes. (Quite frankly, I hadn't expected to see that in New Jersey, but that's on me.) Much of Elizabeth, on the other hand, had a much harder edge to it. Don't know if it is still that way. I had new respect for my buddy seeing where he grew up.
If you don't habla Espanol you would struggle to navigate both communities now.
