The July/August 2021 issue of Dan and Amy Dawdy's O Scale Resource contains two short articles about the convention. There's also a video link showing more of the convention and a couple of the layout tours.

very low sound levels so crank it up after the music fades out (and since these are layout tours, there's a lot of background chatter.) Also I have
no clue who's dispatching the A&O in the vid shot on Thursday. I don't recognize him.
The banquet was not shown in Dan and Amy's convention coverage. Some folks in the photo below had to decide whether to watch all of David's presentation or turn around occasionally to finish their cheesecake desserts.

And a correction in an earlier post of mine in this thread: David informed me that it wasn't Bill's first rodeo as dispatcher. My error. Regardless, anyone who wants to operate regularly is welcome to sit down with myself or another dispatcher to learn how to play the Grande Wurlitzer.
