Actually i did write and asked them to look at mapsands and suggested the cost benefits versus a massive 600 mile physical wall. In their last debate Hillary and Obama agreed a virtual fence is less obtrusive and invasive for property owners. The problem for us is our government is in bed with boeing which has a contract to do some virtual fencing for zillions more than the cost imo of mapsand systems. And reportedly boeing is way behind schedule building it. More news i expect will be coming out as the immigration debate heats up leading to the presidential election. But don't listen to me "i'm just an 800 lb gorilla".
