The entire length of the Leslie St. spit is made up of "clean fill". Iron girders, construction detritus, demolition junk like these wave-rounded old bricks. All topped off with some kind of substandard topsoil that is slowly getting better as the years pass.

What started out as some kind of garbage dump one day became a haven for thousands of birds and a stopping off point for thousands more migrating ones. It's a neat place to bike. I was testing my tendonitis-y foot after two days of resting it.
