This year, like so many years previously, the kids LOVED being able to set up the train around the tree. This train has become a loved tradition, and unlike years before, I think it was set up almost a completely different way, every other day. 
(The only reason it changed was because the two youngest would ‘play’ with the awesome tracks set up by their older brothers!) My only regret was not getting more pictures, as this year there were consistently two levels!
