I don't recall seeing the other car. But each of the two times I was up there I was only interested in the Bobtown car. I need to visit the park again and actually look more at what is left of Berlin and at the IIcythosaur excavation site. If I saw the car, I may have put it aside because it was standard gauge size and not of interest.
The first time I was up there was 25-30 years ago and the shed was over the Bobtown car at that time. I took slides and we took some measurements -- I was up there with Dave Garcia on a week-long trip through Central Nevada prior to one of the V&T/NSRM symposiums.
Second time was a few years ago and I stopped by the little park office and while talking to the State Park Ranger mentioned the Bobtown car was my reason for being there. He did not know anything about the car. But, a voice from the back room advised him that yes, it was there, and where it was. This second time I was taking digital photos.
