windycitysaint,
Really nice story. Since your goal was to get all the cars to complete your friend's set, I'm glad you were successful. When I first read the story I counted the number of display cars in the picture and saw you had all 11. I was impressed, because as Mark pointed out the museum car (#111) is very hard to find since relatively few were made. Great work finding them all.
Now, don't be like me. My set is in storage and has not been run as a whole train. I hope you can run your set soon - and don't forget to take pictures/video.
