Spoiler--Upcoming Event (3/1/2008)

They just had an outdoor lockdown and when they came back there was an 
envelope on the kitchen table for them to read once they had all gathered
in 
the living room. It said that sometime in the next week they would hear a 
distinct sound and to gather in the living room for further instructions.
It 
also said it could happen at any time and to expect the unexpected.

Oooh...suspense!!!
