I'd go bigger and try out a big city. 30's the age to do it. I know for New England, Portland, Manchester, etc, are cities, but anywhere else on the east coast they'd be considered tiny cities or big towns.

That said, from what I've seen of Manchester, it looks much better than most places in NH to be single at 30.

It has nice spots and plenty of bars and restaurants, but as a city, it's definitely on the sad run down side.
