Speaking of observatories, the beautiful old Yerkes, belonging to the U. of Chicago and where many well-known astronomers studied, is more or less going out of business next month:

Yerkes is a wonderful place and instrument, but, there are lots of amateur astronomers with better equipment in there back yard than the scope there.
And most are in darker areas.
It should be preserved, but, unfortunately, it’s not good enough for useful science any more :(
