I won't.




Let the sun's rays do the walking! During the Geronimo campaign, the main station was in the center of the Ft. Bowie (AZ) parade ground. Messages were flashed to the summit of Bowie Peak, immediately south, and then relayed to other summits in the network (like present day Heliograph Peak). Labor intensive, but it worked.

Signal mirrors are still a very effective signaling device - light, cheap, and easy (during daylight hours, anyway).
