Updated 8/28/2018:
Haven't gotten a ton done over the past couple of days. Yesterday I managed to get through a retina exam without any laser surgery repairs!
I spent some time gluing the Chooch Large Cut Stone segments (allegedly peel-n-stick   back onto the stone arch.
I also reworked the RR-Track plan of the river area to show the bridge piers and widen the river. For Panhandle 1.0, I used a rippled (tempered) glass sheet (approximately 6' wide) for the river surface. The new, more prototypical and more accurate size of the river (8') means this is isn't going to fit. I am likely to try selling it. I expect it will make a good river or lake for some layout somewhere.
More when I know it.
