Open Walls Baltimore, the ambitious street art exhibit put together by Gaia, is taking shape in Station North. In March, the large-scale artworks started going up around Greenmount West, Barclay, and Charles North, and the work continues through the end of May. We're running an Open Walls story (with photographs by Martha Cooper!) in the June issue, so keep an eye out for that. In the meantime, take a drive around Station North and peep some eye-popping murals.
