This has reminded me of the Hurricane that hit last year on the east coast. My brother was without electric for at least 4 days (Southern Maryland). His neighbors who had generators never bothered to offer to loan them out so that others could make hot water and keep their Refridgerators and freezers cold. I thought that was pretty shallow. My brother loaned out his chainsaw and helped his neighbors cut trees up to clean up the mess. This was a new neighborhood that had block picnics etc...
I would definately loan my generator to my neighbors for long enough to keep their fridges and freezers cold. I know people here in WV that have went without power for days due to ice storms. That is what they did, went around with the generators to help each other out. Of course I like to think that most of us here in West-By-God-Virginia are good folks!
On another note, My brother realized that he could power the electronic switch of his gas hot water heater with the power converter in his truck. He ran that to get his hot water, jumped in the shower and at that exact time the electric came back on.
Now I know this wouldn't work in N.O. because this it will be a LONG TIME before things are somewhat livable.
I'm just trying to make the point of please don't forget to help your neighbors if you can.
