While some people still like to claim "Idaho" is a Shoshoni word for "gem of the mountains," the Idaho State Historical Society is unequivocal about the origins of Idaho's state name: "'Idaho' is not an Indian word." It was invented by a politician prior to the Civil War and passed off as a Native-American phrase. Oh, well. Made up or not, the Gem State is still a gem. Celebrate your Idahome pride at noon, Friday, March 4, for the annual Idaho Day Celebration at the capitol. Featuring performances by Opera Idaho's Jena Carpenter and the Longfellow Elementary School children's choir, a speaker and proclamation by the governor. Later in the day, rustle up the kids and hop on a wagon train at the Ada Community Library Hidden Springs Branch for a trip back in time.
