Before the apocalypse, this was an equipment store where tractors and other such farming items can be purchased.
Glenn, Nicholas and Heath arrive at here which is located on the walker-herding route. Glenn devises a plan to kill the walkers inside so their noise won't draw the oncoming herd off-course. He tries to lure the walkers out the front door only to find it blocked.
Glenn formulates a new plan to kill the walkers in the tractor shop. He tells Nicholas to stay on the sidelines and radio Rick if things go south. Glenn breaks a window at the trailer store and, with Heath's help, shoots walkers as they pour out. When they become overwhelmed, Nicholas steps in and helps kill the walkers.
