First, Bergen is a wealthy bedroom community across the river and NORTH of NYC, so it's not close to Central Jersey. That's a nice area, too, but in a ritzy, posh, cul-de-sac kind of way.
As for the comparisons of Nebraska and Central Jersey, I'm not familiar with the mountains and mountain trout streams in Nebraska? Where are those? I suppose you could also take a train from Nebraska to Philly or NYC, but it won't be a "day trip." I'm also not aware of a lot of forests in Nebraska? I didn't mention it as an attraction, but I'd also put the dining options way up on my list of favorite things about the area. If you looked at every cuisine option available in the entire state of Nebraska, I suspect that there are more within 50 miles of the Rutgers campus than in all of Nebraska combined. Finally, there aren't a lot of options in Nebraska for ocean beaches.
Thom, the way that you bag on all of Jersey--as though there's NOTHING worth seeing there--makes me think that you really haven't spent much time there, and whatever time you did spend, you were likely just passing through. Am I wrong?
