Being a retired electric lineman I have seen first hand how goofy folks get when they have no power or fuel.Back in 2003 I believe about 5-7 States lost the power grid for 5 days.All of our sub-stations here in lower Michigan had no electric.I was on call trouble shooter and people were wigging out.After that little episode we purchased 2 gravity fed 300 gas/diesel fuel tanks and a 17 kw propane whole house generator.Glad we did..
