If you were born in the Boston area you must have at least a vague memory of someone bouncing a baby on their lap singing the "Trot, Trot to Boston" song. Although there are many variations of the rhyme the end result is always the same...the look of anticipation upon the child's face before the " in" backwards between the legs with full trust and assurance they will never be let go.
Boston strong, tried and true, loyal through and through.
