Haha...good question. Brad wrote the song about the snowbirds that live in Arizona during the winter. (Brad performs at the Arizona Opry in Apache Junction) The title comes from a popular bumper sticker seen on a lot of snowbird vehicles. It refers to the change in color of the mountains in the Southwest near sunset...apparently they turn pink...and the snowbirds know it's time to start the party. Tequila Margarita for me, please!
