My biggest concern is based on an ice storm a few years back.

Without a STAND ALONE heater, I could see the electric service go out for two weeks or more and then all the bitty little space heaters from wally world or wherever will be completely useless...

You want to guard agin' that!

Please excuse this "doppelganger". BIG CHIGGER INTERNET picked that moment to foul up while I was posting...
