I got pulled for doing 72 on the road between Portland, Or and Mt. Hood back in '81 or '82. Car wouldn't do more than 67 or 8 on the speedo. Officer looked at my license, turned it over a couple of times and said "Gee, is that an English driver's license?". When I answered in the affirmative he carefully explained about the double nickel and sent us on our way

In later years I've done the trek across the Gulf States from Beaumont /Port Arthur to Ft. Walton Beach - mostly at the higher limit of 65and found I'm one of the slowest out on the road

Happy days!
Cheers,
