Multiple bridges have been wiped out and many others are not passable yet because of flooding. The pontoon bridge over lake Pohachtran (sp) is open only to light emergency vehicles. Many roads are washed out and still flooded. Until they can get the roads opened up, they can't get the supplies forward. One must be prepared for emergencies! Each depending upon the potential disaster.
I'm pretty sure those trucks were either in Alabama or Mississippi. Semi trucks [100's]. It seems to me they need to have smaller trucks to get water/food and ice and generators to as many as possible. There are some roads cleared to So Ala and Miss as of yesterday, reporters got in.
[New Orleans is a different story] If the reporters can get in and out emergency services should be able to as well. Even Fox reporters got out of NO to Baton Rouge and back last night.
I agree, and posted that everyone needs to prepare to be without help for days in the event of an emergency. Of course if your house and car flood you're screwed and have to rely on whatever help may come.
