on the disaster likely approaching New Orleans and adjacent parts of the Gulf Coast, do so NOW. Things are looking to be catastrophic since (as I understand it) the jet stream is too weak to divert or to weaken Katrina. Southeastern Kossacks, now is the time to volunteer your spare beds, sofas and floors. I'm in Atlanta and my phone is 404-378-5424. I hope folks that are closer will add their contact info below.
