Arco was the first place in the US to have its electrical power generated by a nuclear power plant. A neon sign marking the historic fact still glows on the walls of the plant, but only half of the sign is illuminated.
There are many ironies here - the first that only half the sign is lit - (don't put your faith in nuclear) and the second is that when I checked with a staff member he told me that the image sign was no longer powered by atomic power that the congress closed down the plant that was supplying the power.
