Tucked into a dramatic Rocky Mountain canyon along U.S. Highway 6 & 40, the Peoriana Motel in Idaho Springs, Colorado sits at a breathtaking 7,543 feet elevation, its green-roofed units clustered against a snow-dusted pine forest that sweeps up the steep mountainside behind it. This chrome advertising card for the AAA-rated property boasts of "Cleanliness and Comfort" and 31 moderate-to-deluxe units open year-round — a reliable stopover on the road to Denver in the golden age of American road-tripping. Idaho Springs, long known for its gold and silver mining heritage and hot springs, was a popular Colorado mountain gateway. The back carries a cheerful road-trip note to "Aunt Pearl" in Attica, Indiana, dated Tuesday, June 18, 1968: the writer and companions stayed at the motel, are "having a nice trip," report no rain and fine weather, and note they drove 700 miles on Monday. A get-well wish is tucked in: "Hope your leg is better along Lloyd's."
