It is 75 degrees in Arlington on Sunday afternoon but Santa has kept his scheduled stop at Potomac Overlook Regional Park to get Christmas lists from children counting down the days until Christmas. Sam Miller, 6 years old, confided he wants a police LEGO set. His 3-1/2 year old sister, Campbell with her list in her hand, tells Santa her top present is "dress up" clothes for Elsa from Frozen. They inform Santa they will be in Georgia visiting their cousins. Santa says he is greatly relieved to know because he would have gone down the wrong chimney.
