OK, you can't really stroll along most of the Gowanus Canal - there isn't a path beside it. But we did toodle around the neighborhood a bit.
This picture of a concrete works is old-school Gowanus. Gentrification is sinking its teeth into this part of Brooklyn, too, and urban sites are being snapped up as lofts, and some unbearably enormous lots are replacing old buildings. But the process is far from complete yet.
