Greetings,
I make a list first of all of things I need. Next on the list is things I would like. Since I model N-scale I can tell by walking by a booth if the small boxes are present. I hit the booths with N scale first. Look in the boxes on the floor too. If the show is small I make three rounds of the vendors. Books and railroadiana is later. Ho and O is last. You never know what somebody may have. I take a break and grab a drink after the vendors. Finally I get out my camera and visit with the people who are running layouts. I also bring a “binder notebook” with me. It has three rings inside for paper and zippered pockets on the outside. I collect business cards as people hand them to me in one pocket. In another pocket is a magnifying glass. My eyesight isn’t what it used to be. If I like something on a layout I take a picture and make notes.
At the vendors what has worked well for me is asking the person next to me what they are looking for. Then I tell them what I am looking for. Since I look primarily for passenger cars now I can tell by the size of the box what might be there. They can see the specifics of what I need and I can see what they might need.
Helping others works both ways. Recently a gentleman I was next to was poking through the freight cars. I happened to mention that I had picked up a couple cabooses. They were the same kind he wanted. I was able to direct him where to get two for himself. He was telling me how he could not find a Swift reefer car, how rare and often expensive they were. I looked down and pointed out one right below my hand, at a fair price. I made his day. He then mentioned he had something in his trunk I might like to see. He did…most of the Kato Santa Fe Super Chief and some other Kato passenger cars. I could not afford what he was asking
