Cow Appreciation Day is listed variously as July 10th, 15th or 25th. Today's C.A.D. seems to be spearheaded by the Chick-fil-A chain of chicken restaurants who are giving out free meals to anyone who enters any of their establishments dressed like a cow.
WCOW is a Country music station licensed to Sparta, Wisconsin. For many years they simulcast on their AM sister station which also had the WCOW calls (it's now WKLJ, an ESPN Radio affiliate.)
Cows are delicious. Appreciate them by eating their yummy bits today.
