Be careful with the flooded A/S's and parts, microbials from the flooded water (Black Water) can and will cause problems. Some parts/supplies are not worth the risk, don't think bleach will clean this stuff.
The Ms. Coast was devastated with such a major storm.
New Orleans was spared the damage from the NE quadrant of the eye since that went to the gulf coast although the flood water from the levee failure has severely damaged the infrastructure. Many may not know that only about 25% of the population has returned to New Orleans with about 3000 unaccounted for about 6 months after the strom.
FEMA trailers are not even allowed in many parts of New Orleans with the Ninth ward and the East still empty with no utilities or street lights in most places.
