Hi Alex,
It does not seem that long ago that the Jada Railroad was in OGR Run 276! There was a special page in the article about the layout you got for your dad, which I have added to this post. Your mom and dad are fortunate to have you as a son and Dina as a daughter-in-law.
I feel fortunate to have met you and Dina at a York, and know a little bit about what you are going through, so please accept my best wishes and prayers as well.
Yours truly, Dave B
