People at South Pole: Dennis

This is Hutch (left) and Dennis (right). I wrote about Hutch before.
Dennis, after having spent the whole summer season here, is headed
back home. Dennis is IceCube's driller lead. He keeps everyone in
line, including us physicists. He is full of great ideas and is
constantly improving the drilling system. Under him, the drill
consumes 50% less fuel than what was designed, a no small feat.
