Don't move-you have everything here in the NYC area.
I've lived in Pittsburgh, Chicago, Cleveland, and the Baltimore/Washington areas prior to moving to Manhattan.
I have also traveled extensively with work throughout the U.S.. Nothing compares to NYC.
My observations:
-Nearly every city seems small and boring.
-Most U.S. cities shut down after 5PM and are suburban in nature.
-People are nicer and cities are cleaner outside of NYC, however the people are not as individualistic, very clonelike.
-Cost of living is cheaper everywhere else except SF.
What you need to do:
-Move to the city: Manhattan. Get out of the Northern NJ suburbs. There is nothing unique about Paramus, Clifton, or Edison NJ. All suburbs are the same everywhere.
-If you really need to experience something outside of NJ and the NYC area, then move to Chicago or Boston and live in the city. Both of these cities have character and offer many things to do.
-If you're not a city person, then try L.A. (Santa Monica area), or Fort Lauderdale. They are a bit more suburban in nature but you have access to many things in SoCal or SoFla.
IMO:
-San Francisco is pretty but the weather sucks and its expensive
-Atlanta is too hot and humid and its just a big suburb with lots of traffic, a horrendous airport, and too Southern.
-Seatlle's very livable if you can handle the gloom, however, its very pretty when the sun shines. Problem is that its too isolated.
-Haven't been to Dallas or San Diego for nearly 10 years, so I can't comment.
-Phoenix is hotter than hell. You don't see a body until the sun goes down. Wait until you retire to live there.
-Las Vegas is a growing city. It's fun for about three days but then I get bored. Hotter than hell in the summer too.
-Toronto's nice but the winter's suck. People are kind of boring also. Pain in the ass to become a Canadian citizen also.
PM me with specific questions. I'll give you the straight facts about most cities in the U.S.
