I have been at airports all over this area, and I can recall that there was a lot more activity at all of them prior to 2008-9. About that time (not coincidentally the start of the economic problems) the number of hours being flown, and the number of people at the airport, began to drop first gradually, then quickly. I haven't seen it come back yet. My belief from what i've seen: 1) The aging pilot population and the stupid medical requirements are a big reason part of the decline; but 2) The biggest reason is that there's much less disposable income out there. A lot of the people at the airport are financially strapped, and just hanging on for times to get better, when they can go back to what they liked doing… circa 2005-6.
