I saw where there were some bad thunderstorms in the Dallas area this morning (I live in neighboring Arkansas)...when AH was totally down, it became apparent to me that the folks in Grapevine do not have a back-up generator...
It's not 1980 anymore...
Today, natural gas back-up generators aren't all that expensive anymore. They kick in when there is a power outage and kick off when it's over.
Even the dinky, local, "dollar-a-hollar" 3.6 kW local radio station has one.
It might be worth the investment.
