Mrsr58 can likely remind me the name of this location. It's on the tip of my tongue. We went there on the first Vancon location tour back in.... 2009? I recall we were told at the time that the show (and others) film there a lot. For example this was the location of the Jinn's lair in WIaWSNB.
I recognized it immediately because of this photo I shot on that location tour. There was a crew setting up there for another show. For whatever reason this guy was following our group around. I turned around and spied him through the doorway and snapped the shot you see below. It's from the same perspective as the shot above it from 8x12.
