Having lived in Concord for some 14 years you would think I would be totally familiar with my immediate neighborhood. On a 4 mile walk this afternoon I discovered this was not the case. At the end of Williams Rd. I began following a set of abandoned train tracks. These took me past an extensive marsh which I had never seen before and through a tunnel under Powder Mill Road that I have driven over hundreds of times not knowing it was there. I finally arrived at White Pond where I found some very interesting snow patterns in the ice (pictured above).
