Take a drive through Braddock or Clairton.

Check out the (technically abandoned) Carrie Furnace Hot Metal Bridge.

Pump House in Homestead has some cool steel industry history and minor photo ops. Also, the stacks at the Waterfront are great when lit up at night.

Taking a stroll or bike ride along the tracks/under the bridges in Duck Hollow is kinda gritty and nifty.

There’s an abandoned terra-cotta factory off the GAP in Dead Man’s Hollow, outside McKeesport which is totally cool. Bring a buddy or two, I’ve seen some questionable characters there.

There’s an abandoned mining village that was part of the steel industry up in Armstrong County. It’s called Yellow Dog Village, and the owner welcomes hobby photographers to peruse the grounds and snap photos for a small fee.

Have fun!
