I am looking to bring some half smokes back to my parents in Michigan to bring some taste of DC. There is a cart in SE by my work which is the only place I have ever had them (warm off the cart, obviously). How can the half smokes be stored? Is it possible for me to have them without refrigeration for several hours? Also, is there any place to get them retail other than Ben's Chili Bowl? I live near Shirlington and hope I can get them closer to my house.
