Marking Temporary locations

This weekend i attended a two-week long annual event. Held in an unfinished building that will soon be office space, it was 12 floors of artists, musicians and performers. Thousands of people checked out the free event.

As Brightkite is THE location-based social network that places people meeting in locations first, I just wanted to know how to mark temporary locations like this. In my head I can already think of a few more locations where temporary marking might be useful:

DC and Atlanta's summer Screen on the Green outdoor film series
Summer festivals and carnivals
Pecha Kucha nights

These are important because 1) they are excellent social outings and 2) when the event finishes they no longer retain that identity (often, the location may be completely different at the next event). How should these places be marked to maximize meeting people that attend?
 
silly I’m unsure
