I'm going to take exception with that statement.

While there may be no gourmet restaurants in Greenbelt, there is a great deal of social history.

Greenbelt, Maryland is a National Historic Landmark planned community built in 1937 as part of President Franklin D. Roosevelt’s New Deal. Greenbelt was designed as a cooperative garden suburb that would be a model of modern town planning in America. There is a real sense of community there: (many) residents work very hard to keep the original spirit of Greenbelt alive.

I don't live there, but have friends who spent more than 20 years there before relocating out of state. It's also convenient to metro and Marc rail and amtrak stations. The city also operates a fee based van shuttle for seniors and physically challenged residents.

It's not slick and modern, but worth considering if you're the type who enjoys being involved in their local community.
