The Fence

[Brownlie]

Ok, so fence for me is connected with the picket white fence idea. I would probably include that you're talking about a barbed wire fence in the title.

I watch the ghosts in the evening haze --"Ghosts" as standalone idea is somewhat confusing here, but this is an interesting topic.
along the pasture fence. -- This brings to mind the pastoral genre (and some of its variants I suppose) which is somewhat interesting in relation to the picket white fences.

We built that fence fifty years ago,
my back wet from driving pick and shovel, -- Excellent topic. However, this seems to be lacking a smoothness to it.
placing the posts exactly where Grandfather pointed.

My aching fingers like broken sticks
from stretching barbed wire in perfect lines -- Excellent topic, but again it seems clunky.
on posts flawlessly spaced. -- Flawless and perfect seems somewhat redundant.

He towered above me.
"Build it well," he said,
"and it will last longer than we will."

A breeze swirls the ghosts and haze away
from the glistening taut wire.

This topic is awesome. I would suggest trying to put it into blank verse with more exact description. That's just my opinion though.
