Jealous of your permanent layouts!
I set up Christmas layouts and leave them up usually Nov - Feb (thank you to my wife for the generous timeline). It became a full time hobby just planning for the following year. That was a lot of fun in itself
2011 - purchased my first set (Strasburg passenger)
2012
2013 (set it up in the garage with the intent of having a neighborhood bonfire in the driveway, but it rained out). Set up a small trolley layout in front of the living room tv
2014 - dual trains and behind the tv
2015 - even bigger, behind the tree, dual levels
2016 ???
