To the best of my knowledge it was a Smurfit a Stone facility. Receiving inbound loads of paper rolls to create cardboard boxes.
Yes Smurfit Stone was on Pickering Street.They did get spools of paper in for corrugating.
I am referring to Warehouse on Freestone Avenue East of Rt 16 crossing. I remember it being used in the 70's too and also remember switch on the permanently aligned to the siding.
