This year the Kentucky Derby takes place on May 1, so let sunny Spring florals dictate the theme of your party. The menu is a spread of hearty appetizers that should be displayed buffet-style around the living room. White platters look crisp against a printed colorful tablecloth. Silver mint julep glasses are a must. Set the pie out and let guests admire it until it's time for dessert. Make sure the television is visible from all angles — you don't want anyone to miss the race. To let friends know where the party is, stick horse and jockey signs in the front yard.
