Washington is were the capital is but there is definitely more to it that the seat of government. Fact of the matter is, it is where a lot of people prefer to stay these days. People who are looking for jobs, people who are highly educated flock in this part of the Us in the hopes to find good jobs.
Recession may have taken its toll on a lot of states but Washington seems ot be the first place to overcome it. All sorts of jobs, all sorts of industries are improving as compared to that of other states.
The mere fact that a lot of moving companies are found in the place means there is a lot of market for people who are moving in the city as well as its neighboring place. It seems as if people are willing to live in Washington or in places nearby in order to get to work in the morning and go back home at nights.
