Worm tracks

These are not something you see every day. Nor often after a rain, either - unless you are looking for them. I spotted this in the muck at the edge of a sidewalk this morning on my way to the GO train. We have had a few thunderstorms come through during the past two days and nights. They sure bring out the worms. It was a wormapalooza out there.

The lines remind me a bit of the Nazca Lines in Peru
