Finally got down in the stack far enough to build the last grain bin for the elevator. Took it out to the layout and set it all up and realized that I will need to take the piping back apart to move it for paint and ground cover. That's what happens when you rush I guess.
Put lights in the next building in the paper mill and tested them out. Hoping to put lights in a building a day until all the built buildings are done. I would say that I have learned to light structures as I build them, but I only have a few buildings left and I'm not planning on building another layout after this one =p
