Benji-- "pre-heating" means that you need to hold a match to it first.  
It won't spontaneously combust. Flammability rating 1 means "flash  
point over 200F." Tyvek burns at 660F. (330C)

I suggest that any signs in the stairwells be limited to 8.5x11 (easy  
to shoot through inexpensive laser-jets). Based on taking the stairs at  
Arisia for years, most fen know where they're going, and the pocket  
program has done a decent job of refining the con maps.

  And I thought the primary heat source at Arisia was relocated to a  
different hotel?
