It sounds like you were there as a dealer, I was a participant.
I do not want to digress this thread any further, so please read what I write below just for what it is…
Most conventions I attend are Wargaming, Cosplay, or “Comiconish” in nature. These are always a blast, people are having a ton of fun, and any poor outsider that mistakenly wanders in will quickly be recruited to become one of the group. He will get a Mario Hat on his head, dice in one hand, a beer in the other, and the next thing he knows is he is commanding the Republican Guard in the Battle of Waterloo.
When I attended Brass Expo, I was an attendee, but I was treated very much like an outsider. I would have thought I should have been the Belle Of The Ball.
I had just started buying brass, I had always wanted brass, and I was enthusiastic about being there. My career was on a rocket-trajectory, and I had plenty of diposable income to spend on my new treasures.
When people found out I only had three brass locomotives, five cabooses, and a couple of covered hopper cars I was treated like a tenth grade dropout at a Mensa gathering.
The way non-convention people at the hotel were shunned away when they showed curiosity was a shame in itself.
The dealers did not want to talk to me, and other attendees dismissed me entirely.
I do not think I met you there. You have always been a bit of an heroic character to me, so I believe I would have been excited if I saw you.
Anyway… it was a wasted trip and a bad experience for me.
