4)Once I had digitized and rasterized this layer with all the
                military lands, I had to reclass the layer as a boolean image.
                I was then able to overlay (boolean - ) this image with
                'citylakeworkbool' to produce an image where the military
                areas are excluded from the areas that have been selected
                so far.  Again reclass was used to create the final boolean
                image
