The writing on the pink building is blurred and I am sure it was hard to get the screen capture. Bart is skateboarding across the town and in doing so gives us a tour of the town, in sorts. I think the writing could be "Soda Pop" a sign to indicate an ice cream shoppe where people buy ice cream sundaes. The type of place typical teens hung out after school in 1950's comedies. Perhaps it's a nod to these long ago and simple times in the typical towns across America, but nothing is simple or typical in Springfield, is it?
