I managed to find my old sketching kit yesterday, and measured off some 4x6 rectangles in the sketchbook (last used in 2014). Then I wandered off into the Industrial Refuge this morning. There's hardly anyone there on a Saturday morning, just a few runners and bikers, and people camping in their vehicles. It wasn't too awfully hot yet, but hot enough that I only sketched from spots in the shade.
First off, I did a water tower on top of a building near Montgomery Park. I've gazed at in for years while waiting for a bus, but never had time to sketch it. Because, well, buses.
Then I walked down to the ESCO office building and did a bit of 'art' in their parking lot. It could pretend to be sculpture, but I suspect what it really is is an old rusted drill bit.
And then, just a bit further to capture the last remaining bit of ESCO's old No. 1 foundry.
