We got the run-in shed done (it was supposed to be temporary housing for Rico until the barn was finished, but then he got hurt and can't come home til the barn is done because I need a dry place to keep him when the bandage is on). So we decided to get the first load of hay into it, since I was worried by the time the hayloft was finished, the weather might not make hay easy to transport. 131 bales loaded on the trailer, and put in the shed. (And after, I felt like I was too old for all this work!
) Keep your fingers crossed that it stays good (it was very dry to begin with, and it's up on pallets) We had to stop once on the way home and add an extra strap! 
Here's the shed - while I was hanging the waxed canvas tarps (they are supposed to breath) a 10 x 12 and a 10 x 8 so that there is overlap that the snow can't get in. Or that's the plan, anyway. I imagine I'll be moving it down to the barn by toboggan at some point!
and after all the hay was in. Just barely fit. 12 x 16' shed, 7 feet tall (inside) at back, 10' at front.
Agree, once weather gets consistently warm (July 2017??), clean and lightly sand down the T&G and apply the spar urethane and you'll be good to go. Good that you are getting photos of all the stages; over time you'll forget where a wire runs or what is behind those walls just when you need to know! And just think, with all the $$ you saved buying used stall doors/hdwre, it offsets the costs of other materials you had to splurge on! Circular reasoning at its best.
