Went for a stroll around the Middlesex Fells Reservation in Medford, MA tonight. Left around 16:00 giving myself just enough time to get to the spot I had in mind before it would get too dark. In the East portion of the reservation, the area East of Spot Pond divided by Woodland Road, holds a reservoir with a widen trailway enabling you to walk directly around the whole thing. Upon coming up to the reservoir, I noted dusk was fast approaching and quickly got ready to catch the sun laying to rest. Luckily I brought with me my Streamlight headlamp I picked up at Test Equipment Depot to illuminate the paths leading me out.
