I'd never heard of H.E.B. until yesterday. Those guys (a TX based grocery store) have a disaster response team that includes a mobile kitchen to serve hot food. And from the looks of their convoy, a couple good size generators. They've already cleaned up, restocked and opened all their stores in the gulf coast and are giving out hot meals, water and ice.

My company HQ is in Houston. They're on the 4th floor of a building so their offices are okay, but the first floor is flooded and the building is closed. They hope they'll be able to get back in after the holiday weekend. A few employees had to be rescued by boat and/or helicopter from their homes.
Stories like HEB, Mattress Mack, the Cajun Navy, and similar things we're seeing in the news make me optimistic that the people in the path of the massive devistation will ultimately be okay.
