Apprentice stackers

I recently read about an installation at the Ford's Theater Center for Education and Leadership that consists of 15,000 books representing some of the literature about Abraham Lincoln. The tower is over 30 feet tall (image on the left). It immediately reminded me of our Senior Challenge last year when a handful of intrepid senior students build an arch of books (image on the right). I had no idea we might have qualified for an apprentice program!
