Oh, that reminds me of my college days, which were only a couple of years ago! Just watch your butt for the cops and vagrants, and don't do anything incredibly destructive or stupid.

I don't have much to say on the flashlights, but if you have a digital camera with flash, bring that, too! The flash of light amidst almost complete darkness made looking at the pictures later really interesting - like revealing a surprise.

You might also want to bring some rope and your work gloves. I say that from experience.
