Peter, I have enjoyed watching trains run on your present layout, but am really looking forward to seeing what you build in the attic. Now that you are retired, you should be able to move along at a very quick pace! Oh! I'm retired, and my layout progress is crawling along at about the same speed I was taking down Christmas lights and Nativity display this warm (35 degrees) afternoon.
Just kidding, follow George's advice and don't get in a hurry!
