Yeah, potatoes and blah, blah, blah about natural beauty, which we have in spades, but we are the Gem State, because we have a huge mining industry and a person can find industrial diamonds, sapphire, rubies, opals, quartz crystals, geodes, petrified wood, gold, silver, copper, lead, and molybdenum in Idaho among other ores and gemstones.
Before planning your next vacation to Idaho, read up on Idaho law about claim jumping.
