So if the dollar collapse how much to you think a barrel of oil would cost? How much would a gallon of gasoline cost made from that oil?
I don't think this will matter Kartographer, even though I know the point you wish to make. I know that your preppers thread appeals to a wide margin of folks, and perhaps I am within that margin - barely.
I do not foresee the availability of oil and gasoline at any cost, at least not within the cost that Me and Mine would be willing to pay.
I think we are going to an unforeseen place.
