Today we finished all of the crane work at Site #3. We started this morning with the fork and the primary mirror cell/center section/focus housing bundle, and after lunch we lifted everything else: counterweights, Dec drive, electronics rack, trusses, and lots of boxes using a nifty cargo bag that Liliana provided. We will start on Site #1 tomorrow morning.

Here are some photos. Not too many today, since most of them look like those from the work at Site #2.
