When German-born August and Charles Trabing came to Laramie in 1868, they began selling goods and hauling supplies to settlers, mining camps and especially Army forts around Wyoming Territory. Their operations expanded for 15 years, with annual revenues sometimes topping $1 million in today’s dollars.
Early mail pilots eyed roads and railroad tracks as they flew. Soon, the U.S. Airmail built a transcontinental system of night beacons and landing fields. In 1931, low-frequency radio signals from Medicine Bow were the final link–like the railroad’s golden spike 62 years before—in a navigational chain allowing on-schedule, cross-country, all-weather flight.
