Bordered by the Canadian province of British Columbia to the north and the U.S. states of Montana and Wyoming to the east, Utah and Nevada to the south, and Oregon and Washington to the west, Idaho is twice as large as the six New England states combined. With an abundance of scenic mountains, lakes, rivers and outdoor attractions, the state draws more than 20 million tourists eachyear. Idaho produces more potatoes and trout than any other state in the nation, and is known as the “Gem State” for the 72 types of precious and semi-precious stones it produces—some of which are exclusive to the state. Its state capital, Boise, is also its largest city with more than 200,000 residents.
