A different kind of footprint.

I got out of class this morning and saw a student slowly whirring by in his power chair through the slush and snow, leaving two parallel lines trailing behind him amidst countless footprints. Walking in the opposite direction, I followed the lines he left... the only perfectly traceable sign of someone traveling down the walkway. They were so distinct. While the hundreds of shoe sole imprints overlapped and slushed together, these "footprints" sliced through all of them effortlessly. I thought it was beautiful.
