John, an automated horn wouldn't be a bad idea for the future. I'll have to add it to my long list of future plans . The layout generally runs in a sort of "auto" mode where the power is turned on and off through the theater's light board. As a result, everything is indeed conventional under normal conditions. We do have a Legacy Base wired in for when we decide to put it into "manual mode" and run trains ourselves during the shows. That's typically the only time we run anything with sound.
I have a couple of the great MTH Christmas flat cars with the lit trees on either end, but I'm a bit greedy and enjoy running them under my tree at home too much to leave them there. I generally bring them along if I take anything to run in person though. I definitely wouldn't mind picking up a couple more of those at some point as they're some of my favorites.
Skip, thanks for the compliment. That's certainly one of the things I like most about doing this display. Although I enjoy the comments/compliments received when I share progress reports on various forums and social media, the true satisfaction is seeing the enjoyment our patrons get out of seeing it. We've had people asking for weeks as to whether or not we'd be resurrecting the display this year after taking last year off. Although we're not out of the woods with Covid yet, I think it's been nice to have at least one aspect of our normal life back for a little while.
Kazar, please feel free to swing by for a show. The layout is generally up well past Christmas also so you'll have some time to see it yet. Paul unfortunately was finally forced into retirement due to his declining health a couple of years ago. He was certainly an institution in the neighborhood. We're now renting the space his shop was in to a young woman who is continuing to run it as a barber/salon type of business.
