I got to the Urban Nature Walk early this morning and HOLY CRAP this guy rolls up on his homemade summer dogsled.

He and the dogs had done the 4 mile loop around Ponkapoag Pond and the dogs were hot and ready for a dip.

He runs the dogs competitively with that thing. He said it's a unique sled, made of mountain bikes and sheet aluminum, and only weighs 40 lbs.
