A sub-category of this topic I forgot to touch on in my previous post is of the "York Magic" variety.
On either my second or third York as a table-holder in Blue Hall, I was enjoying a rare lull in traffic as I watched over both my and my brother's tables (he was out walking around). I glanced across the aisle and spied a very small number of Weaver boxes on top of my neighbor's stacks of boxes containing mostly Atlas, Lionel and MTH rolling stock, and on a whim, I checked them out "just in case." Turns out, they were the remaining 2 custom-run Weaver Apache Powder boxcars I needed to complete my set, and for which I had been actively looking for for several years. And at a bargain price, too! I was so excited, I probably came close to ripping out my pocket as I pulled out my money! Of course, since then, I see these cars everywhere at prices all over the map, but just seeing them out in the wild still brings back that special York memory.
