On Fathers Day this June placards were placed in my city at just about every corner that had a stoplight.

Fathers Day...Free ice cream for Dad bring him between 7pm and 9pm

Must have worked pretty well because the placards have now all been replaced with 2 for 1 ice cream every Tuesday between 7pm - 9pm.

Giving Dad free ice cream is a great ploy as the kids are going to take him and they are going to want it too..... win/win promotion.
