The whole idea of a wall is ridiculous. So we are going to use the same approach that China used in the sixteenth century to build their wall? I think, in this day and age, we can come up with a method that actually uses today's technology to monitor our borders. A wall would be a huge eyesore, require that we take property illegally from our citizens, split properties in half, ruin the beautiful scenery in several national parks, and be a death sentence for some species of wildlife. Doesn't surprise me that the guy who came up with this idea only has a fifth grade vocabulary.
