Sounds like a great opportunity, Bob!

Some random thoughts:

- think outside your personal box
- shoot at odd angles to maximize strangeness
- shoot small details: locks, bars, wicked-looking metal projections
- water dripping down walls
- rust stains that might be blood
- hope for interesting clouds for exterior shots, else minimize sky

For some people shots, pick a subject or two (perhaps 'attractive', perhaps 'gritty-looking'h and track them (think elk!) to try and capture some evocative facial expressions.

Have fun!!
