When Ike became Pres., he had the super highways built from sea to shining sea. What he didn't say at that time was they were built to allow war planes to land on them. Make sense and few knew. By golly 50 years later that is what's happening and I'm sure it has happened before. But I don't think they accounted for the overpasses .... eeeck!
I'd bet there's always another unspoken planned vision when anything is done under the name of "for the consumer." So, one time for the record, down with ethanol !!!!
