There are many economies that survive without a Navy base on them.  Take San Juan county.  

It is one thing to get a base, but then to support increases that reduce quality of life for citizens who live around the base is placing money from the federal government over quality of life.

I do understand that a whole economy on the north end has grown up to be dependent on federal dollars for survival.  It's not like other manufacturing jobs rose up with the Navy - just big box retail stores and city and county government.  

Island county should be trying to attract some time of private industry instead of begging the U.S. Government for more from one source of income.
