THEY’RE BACK: We haven’t seen the hickory tussock caterpillar all summer — that is, until last week, when we spotted one hanging from a tree on the Richard McDowell Trail by the University of Pittsburgh at Bradford.

We’ve seen several since then.

If you don’t know what a hickory tussock caterpillar is, they excrete a chemical that causes a rash on human skin. They are white, fuzzy caterpillars with black on them. Watch out.

ELEVATOR: Donald Tracy of Rew remembers when the elevator was put in the Terminal Building.

Donald tells us that when they put in the elevator, he was on the crew that drilled a column using, of all things, a drilling rig, making space for the hydraulic cylinder.

John Depetro had an office for years on the second floor of the Terminal Building, and Donald helped John moved his equipment out when John moved to the Odd Fellows building.

It was about that time they put the rig in the building.

Joyce Ostrander’s father-in-law, George Kloss, ran the elevator in the Emery Hotel when the University of Pittsburgh at Bradford was using it as a dormitory. She wasn’t sure when, but she thinks it was probably in the 1960s.

“From there, he went over to the Odd Fellows building,” she said.

George started as an elevator operator after retiring from Dresser, but worked into his 80s, according to Joyce. She estimates he worked about 20 years between the Emery and Odd Fellows buildings.

Sandy McClintock, too, remembers seeing George operating the elevator in the Odd Fellows building when she would bring her children to see Dr. Silverstein there.

They would ride the elevator up to his office.
