Does anyone know what this sign is for? It is the absolute best hamburger any where in the USA (except for my husband's on the grill) Whataburger started in Corpus Christi, TX and has found it's way into other states. California needs to take lesson from them. In and Out does not hold a candle to Whataburger. But here in Kentucky where we live now, they have not a clue to Whataburger or In and Out. Just the main chains adn that is too bad. WE MISS OUR WHATBURGERS!
