There's the glass sculpture in Dunbar, and some beehive coke ovens as well.
Ohiopyle is a cool little town. Make sure some place is open for lunch before you ride over there though. I guess it's a little over 30 miles RT tho.
Perryopolis has some history, and Jason Momoa recently shot a movie there.
Sager Mosiacs in Whitsett is cool.
Rivers of Steel: Carrie Blast Furnaces looked pretty amazing. Make sure to make an appointment.
Pittsburgh has cool stuff and is less than 30 miles RT.
