The walls move out to the yard.

Last night I got two of the four walls up on the cement pad in the backyard.  Careful measuring where to drill the holes in the wood for the bolts in the pad worked out well and everything lined up nicely. This photo was taken tonight before I put up the other 2 walls.  Measure twice, drill once - and again it all lined up well.  
Photos of the 4 walls later.  The shortening days are a problem, so I had to use a flashlight to finish.   Alex the construction supervisor cat is seen in this photo.
