Got it on the ground!
We're now in the position of having the 'feet' on the ground, and *just* need to stand it up. The ropes are hooked up to a metal cable that runs through a pulley in a redwood tree to the north of the house.
The ropes will NOT be enough to pull it up. We'll have to keep pushing from below.
We're also putting the girts in place, so that when the middle section stands up, they'll lock right in. They're heavy too, so that'll take a while to get in place also.
