This episode's guest is a man who brings a lot of happiness to Boston: the artist known to everyone around here as Sidewalk Sam.
"Sidewalk" -- "Sam" seems to be his alter-ego's last name -- was trained as a fine artist at Boston College and Boston University. He then went to Paris to work at the Louvre Museum before returning Massachusetts have his work exhibited at the MFA and the Institute of Contemporary Art. Of course, this artistic pedigree lead directly to him giving it all up to draw chalk pictures for people to walk on.
It may not make sense if you haven't met him, but it all comes together when you first experience his loving, friendly, and unreserved style.
