Thanks! I caught the 1060 Addison reference from the Blues Brothers. Was thinking I was behind the times on something similar here.

123 because, well, it's in order. And Maple street because there's one in almost every town in America. One could also use 1st St, Main St, Oak St, etc. Maple has a nice ring.
