[TCML] live pigs on the ground

[David Rieben]

Hi Dave,

After reviewing these images a bit closer I see that you
are correct and that I was initially mistaken about the
surface that these pigs were sitting on. It had appeared
to me that these pigs were sitting on bare ground but a
closer examination of the thrid of the four images clear-
ly does show a narrow concrete slab peaking out from
the dead grass and weeds. I guess the foilage is dead
because of the groundskeeper that Mark advised to
be careful about spraying around this installation ;^)
