TAC,
Having just completed another year of a Thanksgiving Weekend Train Show, I understand the attitude of not wanting to share. We are always amazed with participants at trains shows that don’t talk to the people looking at the layouts.
Whatever, we go to have fun.
I believe the attitude of the “sticks in the mud” participants is their loss. We live amongst them or around them. We’ll give them a little time and then they become like a stain on the floor, you walk around it or over it and realize it is unimportant and only distracts from the overall experience.
