Well I rounded out my day with a lap of the white, red, silver, and blue halls and several laps of the orange hall. I also stopped by Altoona Model Works at the suggestion of @jhz563 and found their structures to be really amazing.
Maybe Lionel could partner with them to make a model of the Altoona engine test plant with a kit to make it come to life with Legacy/TMCC.
I finished the day sitting in the cafe area chatting with a few members after spotting @Traindiesel and @gunrunnerjohn. I didn't catch everyone else's name because the hall was a bit loud and some youngster was working the throttle pretty hard on a nearby display. If you were sitting there, apologies for that and tag me if you're reading this so I can put a name to the face next time!
I will say this York wasn't as grandiose as those in the past, but it was the first I attended alone as my Uncle couldn't make this one and it was nice to make a few acquaintances along the way.
P.S. I picked up this sweet Altoona PRR station replica from Iron Horse Engraving. I took notice of a replica 5550 keystone there too and chatted with the proprietor about the ambitious T1 Trust project of which he seemed about as big of a fan as I am. Can't wait to see that project steam up!
