1916Casper Weekly Press: April 7, 1916
The Casper Weekly Press was apparently the Friday edition of the paper.
1917 The Casper Daily Tribune for April 7, 1917. No panic here.
The Casper Daily Tribune is almost a shock compared to other papers in the state this week. It didn't seem that worked up about the war.
It was starting off with the bold declaration that Casper, in the midst of the World War One oil boom, was "the city wonderful". It predicated a population of 15,000 in the next few years, which may or may not have been a pleasant thought to long term residents, but as things would play out, it's prediction was in fact lower than that which the city would rise up to in the near future. The refinery depicted in the photo on the bottom of the front page was much of the reason why. Already, as the paper noted, residents who were returning to the town after an absence were shocked to see how much it had changed.
Major Ormsby, that was his name, not his rank, was interviewed in the paper about radios. Ormsby was a local rancher who is remembered today for a road north of Casper that takes people to a rural subdivision, although it might be more recalled by some as it goes past the oldest of Casper's two strip joints (shades of what 1917 would bring in there). At the time, however, that was all rural land and apparently Ormsby had a radio set there. He was interviewed due to a rumor that his radio was going to be taken over by the Navy, although the article notes he'd heard no such rumor. He also hadn't listed to his radio for a long time, apparently. The paper noted that the nearest commercial station was in Denver, which was true, that being the very early predecessor to KOA, which is still in business.
As the US plunged into war, the Leader was proclaiming that Wyoming could furnish the finest cavalry horses obtainable anywhere.
Actually, it already was.
Wyoming, in addition to experiencing a petroleum boom, was also experiencing a horse boom as horse ranchers, quite a few of them with English connections, had been been supplying the British, as well as the French, with horses for the war for years. Starting with the Punitive Expedition, it'd started doing the same for the United States. Not all of these horses were "finished" by any means, indeed most of them were not, something that came as a shock to their European users who were surprised by how green these horses were.
Added to his, of course, Wyoming had a major Remount station in Sheridan Wyoming, right in the heart of Wyoming's horse country, which would continue on through World War Two.
In that other boom, the oil boom, that had become so significant that the Leader was quoting the prices from the Casper exchange now on a daily basis.
1922 Ground broken for the town of Parco. Parco still exists, but it is now known as Sinclair, and is the site of the Sinclair Refinery. At the time of its founding, it was the location of a very nice hotel on the Lincoln Highway. The hotel's buildings still exist, but the hotel itself is long closed.
