Dash-7's in the USA?

So I was looking through old picture albums from my childhood and I found pics of me at TPA standing next to a USAir Express Dash 7, in the cockpit, and in flight onboard. I loved that airplane and I have not seen many in recent times at least here in the USA. Does anyone know where I might go within the USA to fly aboard one?

for all i know the army is the only one flying one:

Voyageur Airways flew into LGA a year or two ago on one occasion, but that might turn out to be the last we hear of the Dash 7 in NYC.

Canada Armed Forces have a few though.....

I believe I saw this plane (flying for the US Army) at Elmendorf/Ft. Rich about 2 years ago.
