Bethel Park has a river and is/was near steel mills? I know bethel park to be south of Mt. Lebanon. A mostly residential area now. Was just there over the holidays, hit up south park bmx for a few laps with the kids.I lived in Bethel Park from 1945 to 1951, steel mills blazing and smoking across the river, driveway strewn with red dog.
What is red dog?
