See my initial post on the "Hazmat Responders" discussion thread for background and links to videos of this event...it was pretty awesome. The photos may be a bit out of order..my text was progressive. I tried using the "move" function without much success, so if one photo mentions something related to one you haven't seen yet, click back & forth a few times to figure it out. Later I'll try to get them in sequence the way it was supposed to go initially.
