I'm sorry for being so late. Apparently I somehow managed not to hit the "post reply" button earlier when I composed my update for this morning. At that point, the crane was there and running but nothing had been lifted in yet. When I went back this afternoon, I found that a piece or two had been put in on the north end. I'm not sure if they are going to work this weekend but if they do, we could see half the board done on Monday and finish late next week. If not, then they might not finish until the week after. With the fireworks being cancelled, I would imagine there's a bit less urgency now.
The south board is indeed completely done now. I saw them doing a little work to the ends of the ribbon board area the other day but it didn't seem to be worth posting or studying in great detail. I wish now that I had because I can't quite tell what they did. It seems like they put in two final small sections of ribbon board to fill in the empty areas but I never saw these new pieces and the crane was already gone. The other possibility is that they cut off the unused space but I'm not sure. The bottom line is that it's done.
Finally, the field level board appears to have been finished right under my nose. I'm not sure when they did that but it's done now. I might try to stop in this weekend if I have the time and see if they are working on the north board. I make no promises though.
