Here is a shot of all the trusses up and the framing for the roof completely finished. Whew!
Next, David's dad came over to help with the sheathing. We are VERY lucky to have such handy, generous parents in our lives - thank you guys!!!

Wayne had to heft it up to this little platform, climb up, then lift it up to David, perched on the roof.
Here's a close-up. I didn't want to climb the ladder with the camera, so it's from below.
Here's David up top with the nail gun:
