I remember when you could get the metal cans for a couple of bucks (or less). Hell, the old one gallon metal ones my dad has are looking pretty good. He's got a lawn service now, so maybe it's time to sell the mower and I'll ask for the gas cans.
Also, I saw on Stossel when I was at my folks house that one of the big problems after hurricane Sandy was not only the stupid .gov rules regarding gas stations and pricing, but also that because Blitz had gone out of business that there were no gas cans to be had. People were showing up with anything and everything to hold gas, only to be told "NO, you can't put gasoline in THAT!!"
