Abstract Thursday: "Contact from the Other Side"

Great progress on the work, and today we've broken through the first of the blocked-up doorways.

Of course, when I say "we" I mean John, who's doing all the hard work :) This is him looking through the first drill hole he made, with me capturing it from the "exit wound" side. By the end of today, we had a bigger-than-head-sized hole all the way through.
