Another pic of the white hat guy just emerged: http://i.imgur.com/NFPlOCI.jpg
Going back north where they came from, though this time Mr White hat’s turning on Fairfield (walking back to Cambridge across Mass Bridge?) rather than Gloucester.
He seems here to be alone, with NO backpack.
He’s not alone. The Bridgestone cap guy is in the pix, right behind the woman in the pink jacket.
