In Maryville, there are sidewalks in someplaces and not others, a zip code covers to much area to be specific enough about whatever location you are curious about.
Best is to Google maps, type in address, go to street view. you can take your mouse and go up and down the street and across the street. Really works great to show neighborhood.
Google Earth is another way to go.....Maryville is a FANTASTIC place to live. I hated when this secret got out!!!!
