The shortest distance between two points is a line. In Euclidean geometry, we can draw that line "as the crow flies" directly from one point to another. What happens when we use a grid instead and have to create directions as a car would drive? We will explore pathways with various constraints on a grid from looking just at the "roads" to what changes when various obstacles and obstructions are in the way. Thinking like a mathematician, a city planner, and a traffic engineer, we will discover how to use the grid to help us and how to move beyond its constraints. This circle uses concepts from Getting on the Grid, but can be taken alone.
