So his daughter is selling the place. Wow! What a dream business for a forum member. It's profitable, too! You could probably learn a ton just by digging into the inner workings of that magnificent layout. Perhaps a group or club could buy it.
If I were 10-20 years younger, I would seriously consider a run at buying it. In the meantime, I'll continue to watch the video I bought from their website many years ago now (one of my all-time favorites) and hope I get a chance to visit the layout and new owner(s).
