A double fence, the two fences about 12 feet apart, with razor wire on top of each and in between, and sensors to indicate when people tried to cross would be no big deal, certainaly no more than building a two lane blacktop road. Fred just lost it on this one.
Too long? Too long? I suppose a farmer would say I could build a fence around that field to keep the cattle in but that would be too long. WTH kind of thinking is that Fred?
