"Before I built a wall I'd ask to know
What I was walling in or walling out,
And to whom I was like to give offense." Robert Frost
The looping wall is by Andy Goldsworthy, revival of an ancient craft. The other straight line images (in color and in black and white) also highlight the artistry of his beautiful wall making as the wall heads in a straight line up a steep hill and across an open field on the other side of the pond. Walls may be useful for delimiting boundaries...as long as one can hop over them easily or comfortably chat as neighbors.
