I bought a 1968 Dodge Polara in 1970 when I came back fro Vietnam and was in the army for an additional 10 months in Fort Meade Md, used to drive back and forth at least twice a month from Ft Meade to Syracuse and probably averaged about 75 mph except for the one time I overslept and left NY at 3 AM, averaged about 100 mph that time, I didn't want to be AWOL, made it back to base just in time to change and make formation.
