If you are ever in Baltimore and have some time on your hands, I highly recommend visiting this site of sites to see what the latest bombers have sent in on the tracks. Be sure to follow the point on my map very specifically, as the other areas marked with tracks are not guaranteed to have such easy viewing access:
Mostly Burners, tags, and throw-ups, I did manage to see one Whole Car Top 2 Bottom piece in my days passing through to work at UA's Headquarters. Probably the coolest thing was seeing some chalk-art (a folk-art type of tradition started by "free-riders" back in the day) from as far as San Francisco!
Anyways, I hope you can forgive me for not taking enough photos, as sometimes (see: most times) I like to just appreciate the fact that I am alive in a moment and do not want to ruin it with today's social media obsession with the act of "capture."
As for the photo at the beginning of this post -- at the time, I had a very serious appreciation for the City of Baltimore (and for the most part, still do), and so had to, had to delay my morning commute by 3-4 minutes in order to shoot this gem Character / Filler for a piece I honestly cannot remember (i.e. I can't remember what the graffiti artist's name was in its entirety). The control over his/her paint can to display such elegant cursive lettering over a rustic patina seemed to conjure the City's spirit in a way I could not resist (hint: notice the interplay in juxtaposition between "heart" Baltimore and the red letter warning letters "Do Not" - I believe this is called situational humor --- given your experience(s) with Baltimore, what would you call it?).
I will be back in Baltimore again this weekend for business -- if we're lucky, I just might make my way over there for some shooting....
