Tunnel to Boston (Posterized Photo)

Here's another image from Sunday's very quick trip into Boston.  This was literally drive down to Galatea Fine Art, pick up a painting, turn around and come right back home.  But going really anywhere is a treat these days. I was in the passenger seat, so I took lots of pictures, even of the less scenic parts of the drive that I usually ignore, like this view of the Central Artery tunnel, under Boston, as we headed south.  Today I edited the original photo and used Painter to add posterizing effect. You can also see the ice on the windshield.
