Been a few years since I was last able to wander around here. I was in Pontiac, IL yesterday for some family business, had some extra time and strolled though and it was just as good as I remembered it. Easy drive from the Chicago suburbs to see a very well curated display of +/- 20 cars in various period displays and loads of automobilia including a jam packed actual library of reference materials. I know Tim and Penny Dye have participated in MCACN as well. Great place - please support their efforts.
