Hairy, Ethan is a lucky boy....very cool....
I was born in SD and while my Dad owned a restaurant he had farmed befire I came along and had sold the ground to family.  The barn was still standing, so my Dad built me a plywood replica when I was about three.  I had it until I was about 40.  It took a lot of space, so one time when I took a trip back, I took it with me and gave it to the children who lived on the farmstead.  The barn is the only building left from the original place...new house...new out buildings, etc.  My little barn had faded, a door or two was gone, and it said our last name on the hay mow door.  I had not seen it since I gave it to them in the 90's, I figured it was long gone.  When I was back last year, the little who I gave it to now lives on the place and has two young son's.  We had made a point to stop and see the place and photograph some of the stuff, and the son, walked out with it.  It was all repainted and bore his name on the hay mow, the doors all replaced and where my dad had painted on windows he had cut holes and put doll house windows in.....it was a cool moment.  With any luck Ethan's barn will be a legacy like that for his family.  
Good job....great detail and design.
