Tom,
I have never had a train to do list, I was lucky enough to have a family tradition of O Gauge trains at Christmas time. Always wanted to set up a nice size layout so I did after retiring. For a little over 10 years I had a real nice multi level layout, that took up a lot of my game room and most of my home office. Like Pappy my advise is to do what you like, do not procrastinate when you reach retirement age, the fact is most men end up with major health problems sooner than they think, in my case Agent Orange put me down with a major heart attack, that I was lucky enough to fully recover from. I enjoy my multi level living room layouts more than ever now, and they seem to stay up from just after Thanksgiving, till around mid February. I really like the guys and gals here, the OGR has kind of turned into my 2nd home. In the near future I would like to make it over to York to meet Barry, Guns and MartyE, Marty F, RJR and all the reset of the nice people I talk with here all the time. Retirement life seems to go buy 10 times as fast as when I was working as a Special Agent or as a Professional Engineer. I truly love my life now and hope every man and woman get to live the retirement life God has granted me and my wife. Live your retirement for all it's worth.
