Right now there is a big structural fire about a block from my building in Factoria, WA. All of the office peons are watching it out of our 4th floor window
Watching how quickly that fire spread shocked me. I saw it when it was first starting and there was just a little cloud of white smoke. Less than five or ten minutes later the entire building was a giant inferno. Makes me much more respectful of fire alarms: get the hell out while you still can!
