I uploaded a pic of our tour of the La Farge Cement Co., near Allentown,
showing the rotary kiln, which they report is the largest piece of machinery
in the world. Very impressive!

We also went to the Saylor Cement Museum, which is housed in one of the mill
buildings of the Coplay Cement Co. The kiln stacks are still in place, having
undergone some stabilization and some other changes. Neat place.
