Question: When was the MGM Grand built in the largest city in the southeastern part of the state where Humboldt Range is located?

<P0-S0> The Humboldt Range is a largely north-south running range of mountains in northwest Nevada, USA, that extend from the town of Imlay in the north to the junction with the West Humboldt Range in the south. <P0-S1> It is bordered continuously by Interstate 80 and the Humboldt River, largely expanded in the form of the Rye Patch Reservoir in this area, on the west side and by a long and fairly broad Buena Vista Valley to the east, in a typical basin-and-range pattern. <P0-S2> The Humboldts are ostensibly visible to travelers along Interstate 80, especially with respect to the highest point of the range, Star Peak, which with a quite nicely defined tip reaches an elevation of 9,836 feet (2,998 m), located in the center of the north range section. <P0-S3> The midpoint of the range is in the area of Fourth of July Flat. <P0-S4> The Humboldt Range is also noteworthy for having a famous historical town at its base on the eastern side called Unionville, which, for a brief period, was home to Samuel Clemens. <P0-S5> Another historical site, now a ghost town, nearby is called Star City. <P0-S6> Unlike some ranges in the vicinity, the substantial height of the Humboldts allows for a number of continuously flowing watersheds, and hiking the terrain is a somewhat noted activity. <SEP> <P1-S0> When the latest MGM Grand opened on December 18, 1993, it was owned by MGM Grand Inc. At that time it had an extensive Wizard of Oz theme, including the green ``Emerald City ''color of the building and the decorative use of Wizard of Oz memorabilia. <P1-S1> After entering the casino's main entrance, one would find themselves in the Oz Casino facing Emerald City. <P1-S2> Dorothy, the Scarecrow, the Tin Man, and the Cowardly Lion were seen in front of the city. <P1-S3> The Emerald City attraction featured an elaborate yellow brick road walk - through, complete with the cornfield, apple orchard, and haunted forest, as well as audio - animatronic figures of Dorothy, the Scarecrow, the Tin Man, the Cowardly Lion, and the Wicked Witch of the West. <P1-S4> It would end at the door of the city, leading inside for a performance of`` The Wizard's Secrets''. <P1-S5> When MGM Grand began its extensive refurbishment in 1996, the Oz Casino was the first to go. <P1-S6> The Emerald City was completely demolished, and the Emerald City Gift Shop was moved to a new shopping section of the casino. <P1-S7> The store remained open until early 2003. <SEP> <P2-S0> new york city is situated in the northeastern united states, in southeastern new york state, approximately halfway between washington, d.c. and boston. <P2-S1> the location at the mouth of the hudson river, which feeds into a naturally sheltered harbor and then into the atlantic ocean, has helped the city grow in significance as a trading port. <P2-S2> most of new york city is built on the three islands of long island, manhattan, and staten island. <SEP> <P3-S0> A major part of Southern Nevada's economy is based on tourism, including gambling. <P3-S1> The primary drivers of the Las Vegas economy have been the confluence of tourism, gaming, and conventions which in turn feed the retail and dining industries. <P3-S2> The city serves as world headquarters for the world's two largest Fortune 500 gaming companies, Harrah's Entertainment and MGM Mirage. <SEP> <P4-S0> the golden nugget was originally built in 1946, making it one of the oldest casinos in the city. <P4-S1> jackie gaughan at one time owned a stake in the hotel as part of his many downtown properties. <P4-S2> steve wynn bought a stake in the nugget, which he increased so that, in 1973, he became the majority shareholder, and the youngest casino owner in las vegas. <P4-S3> in 1977 he opened the first hotel tower and the resort earned its first four diamond rating from mobil travel guide. <P4-S4> it was the foundation for wynn's rise to prominence in the casino industry. <P4-S5> the second hotel tower opened in 1984 along with the showroom, and the third tower was opened in 1989. in 2000, the golden nugget (and all of mirage resorts' other properties) was sold to mgm grand, inc. (later named mgm mirage).
