a tower!

They got all the plywood on the tower roof today.  Hurrah!  That means
that they're ready to start on the metal roofing.  I think.  And once
the metal roofing is on, they get the windows and put them up and the
house is Completely Dried In.  That's a seriously major step, because
it means that weather no longer affects them.  They'll still need some
good weather to put the siding and trim up, but they'll certainly have
enough of that in August.
