Nature Done Wright

With so much interest these days in deer exclosures  (enclosures designed to keep the deer out), I thought I'd offer this photo of what I think is an old-style deer exclosure along the Bozman Neavitt Road.  

The fence is approx. 6 feet tall, with a foot of barbed wire extending at right angles along the top.

What's more, the base of the fence is set in cement.

Is it a deer fence? Why the cement along the base?
