Where in the World are Grandpa and Grandma? Bring Your Water Bottle

This state is the driest in the nation.  Much of it is uninhabited sagebrush covered desert.  Trappers and traders entered the area in the 1820's and the United States obtained the region after the Mexican War in 1848.  The state entered the union on October 31, 1864, the 36th state.  The first permanent settlement was a Mormon trading post near modern day Genoa.  In 1931 the gambling industry built the city of Las Vegas and it draws visitors from all over the world.  The state manufactures gaming equipment, lawn and garden irrigation equipment and titanium products.  The capital city rhymes with criminal fire igniting and is near the Comstock Lode, the richest known silver deposit.  The leading agricultural industry is raising cattle.
