I have written several letters to the Treasury Department and the Department of Transportation, demanding to know why is it important that a car “stops on a dime”, instead of two nickels or ten pennies? And once again they ignored my inquiry. They always give me the same lame response that they are willing to pay, if I’ll seek some mental health assistance. What is the federal government hiding? Possible coin discrimination? Yep, I think I’m on to something.
