Tired of hearing how much the wall will cost? ME TOO!!! Turn this gripe completely around by making the wall pay for itself and then; continue to generate revenues and create jobs, in perpetuity. Build the barrier and include in its construction; a line of Solar Panels and Wind Turbines along as much of the lenght of the wall, as possible. This will create an ongoing REVENUE STREAM in the generation of electricity. It will also create JOBS! JOBS! JOBS!
