3) I had to digitize a point for the spot where Stan's workplace
                was going to be.  It had to be rasterized and then a buffer of
                20km was placed around it.  The image 'workbuff20' was
                overlayed with 'citylakebool' (boolean + ) and reclassed to
                produce the image 'citylakeworkbool'.
