It's an entirely different approach which might require some drip irrigation, but eventually I will be building a perimeter 'wall' consisting of a similarly tall, stout chain link fence with a nice mix of vines and flowers eventually overgrowing it. If security is required, coils of razor wire might be incorporated(?) But tasteful masonry, especially elegant stonework, is typical of fine Mexican design, and if a Maestro still makes $600/mo, should represent terrific long term value.
