Industrial Charm

Have I mentioned how much I love happening upon charming things in a city? Despite its size (or perhaps because of it), Providence has a lot of industrial charm going for it. These are my two favorite new pieces of graffiti this week. (Don't worry, I took the pictures when there weren't any kids walking by so as not to encourage delinquency. Not that I support it, but it is witty delinquency at least.)

I know it's graffiti, but I honestly love these little bits of character. I fall in love with a place by first finding my favorite running path and then, day by day, uncovering random flashes of vivacity. It's like the whole city is secretly a work of art that, once discovered, is a comforting 'inside joke' as I walk by each day.

What's your favorite mundane-but-charming sight/smell/sound?
