I Walk the Line
Contributor(s): Aimee S. Johnson, Joshua M. Sabloff
Your regular commute begins at your house and ends at your office at the corner of 5th street and 6th avenue. You have been making this trip for years, but you are the restless (or adventurous) type, and you try to take a different route each day. At some point, you start to wonder how long it will take you to try all of the routes.
Oh, did I mention that you have to avoid the zombies?
