"It was mentioned on Smiths show that I-10 west is flooded."
Buses, trucks, cars and Military vehicles are coming in from somewhere and those are using I-10 to get to New Orleans.
I believe that able bodied adults could at least walk out along those road that these vehicles are using to get in.
Waiting in New Orleans is stupid, it is not going to be fixed any time soon and it will be without power for a long time.
Get everyone out.
My local paper printed a map showing parts of I-10 west flooded, and the entrance/evacuation route for the downtown area as Highway 90 around the south part of the city, entering at the bridge next to the convention center.
But by all means believe what you want.
