Years ago I went to a Super Bowl party at the house of my son's friend. Our host took us into his train room where he had a large Lego layout ( Maybe 12' x 20'?) It was a completely scenic'd city with all lego buildings and accessories and had numerous loops of track, switches and trains. I had never seen anything like it.
It was completely enchanting and made me want to immediately go home and make a lego layout. It had the bright shiny charm of prewar tinplate. I lay down and waited for the fever to pass.
