Why wait until the robins are bobbin' to do a bit of spring cleaning? Join Seth and Molly as they dare to enter the cobweb-cluttered confines of Seth's attic and sort out trash from treasure in his dusty collection. Find out which of these odds and ends are salvageable and which should be deep-sixed in the dumpster. Don't forget to bring the Hefty bags and a dust mop!
