I used a Las Vegas billboard space to express an opinion of environmental concerns regarding junk advertising and the ecology. My billboard(s) replaced the scenery behind it that had been previously obscured. The billboards evolved monthly. The first month, the "replaced scenery" was to scale (see Fremont Billboard #1). The next month, the view changed to a closer perspective of the scenery, focusing on natural elements, and so forth, over a 6-month period.
