I was striding down the sidewalk to Joan of Arch when I noticed some tracks in the snow. Students had deduced the route of least resistance and had made their own paths through the snow. As a kid, I would follow the cattle paths on my Grandfather's farm since they were the easiest way up a hill or down a creek bed. I wonder if these college kids know they have this engineering gene in common with cattle? They cut between buildings and through the center of the 'green' slicing seconds or feet off the sidewalk route. Mind you...they are cutting through snow...I wonder how wet or cold feet figure in the equation?
