Gas stations will be closed, as in Katrina, so no gas.
You are right. check my list and you will see a ten gallon container of diesel.
I have a diesel VW that gets me roughly between 32 and 35 mpg depending on the roads and area.
I keep tanked up. The car too.(dont drop below 3/4)
Alabama will have pre-positioned gasoline tanker trucks and electrical generators strategically placed along hurricane evacuation routes from now on.
I don't think that will work during a terrorist attack because things won't be 'pre-positioned.'
