Performing a site walk at the historic Yerkes Observatory

We recently took a tour of the historic Yerkes Observatory. Yerkes Observatory needs some much needed maintenance to get it back up to code and operating again. They reached out to us to see if we could assist in restoring this beautiful observatory.

I'd love to see more about the mechanical parts and how the telescope moves. Ditto the raising floor. Really, the bits one would not normally see on a tour.
