Ode to a Lost Nomad

This past week, it was announced that a long-lost Canadian Northrop A-17 Nomad was recovered from the bottom of a lake. The CNN story can be seen here.

In honor of that recovery, I offer this completely unrelated photo of an Army Air Corps A-17. Obviously, given all the people in the scene, something was going on, but the plane (tail number 26) seems otherwise unremarkable. I really like the hangar architecture, but have no idea where it is. Ideas anyone?
