Came across the below NJ license plate stopped at a light a few months back. I knew he was a Celtics fan since the bumper sticker beneath it said "Red Sox." Although when I was passing him and beeping with a "thumbs-up" expression, he seemed more perturbed than pleased.
I received the second picture this morning via a text. I've seen NY license plates with NY teams on them (Rangers, Islanders, Knicks, Yankees, Mets, Giants, Jets, probably even the Devils and Islanders) but this was really cool.
