Yesterday I drove from Boston Massachusetts to New York, and on my way, when approaching Providence, Rhode Island, I spotted another Ron Paul banner. I really got a kick out of the one on the southbound side because it said to Google Ron Paul banners!
There was another one on the same bridge on the northbound side.
I was able to take a picture of one further up on 93 awhile back:
