So one day Carole and I walked over to this underground parking lot, armed with an SB900 strobe (very small flash) and a roll of latex tape. We brought over a robe that I'd trow over her immediately every time we heard people walking by. 

 

Kudos to Carole for withstanding all the dust, and posing like a champion as I was fumbling around with lenses and attempting to keep the strobe over its tripod. Also, we broke into an empty cage just so we could place the light in a more advantageous position. Exciting!
