At Albuquerque, New Mexico, Denver Thruway connections are made daily with the Amtrak Southwest Chief. Additionally, the Ski Train operated on the former Denver & Rio Grande Western Railroad, which took passengers between Denver and the Winter Park Ski Resort, but it is no longer in service. The Ski Train made its final run to Winter Park on March 29, 2009. The service was revived on a trial basis in 2016 with a great amount of local fanfare. Further development of a mountain corridor rail option, though publicly popular, has been met with resistance from politicians, namely the director of Colorado Department of Transportation[not in citation given]. The Ski Train did return to service under Amtrak with the name "Winter Park Express" in 2017, and currently runs only on Saturdays, Sundays, and major holidays during the winter ski seasons.
Denver used to be a major trading center for beef and livestock when ranchers would drive (or later transport) cattle to the Denver Union Stockyards for sale. As a celebration of that history, for more than a century Denver has hosted the annual National Western Stock Show, attracting as many as 10,000 animals and 700,000 attendees. The show is held every January at the National Western Complex northeast of downtown.
Denver has many nationally recognized museums, including a new wing for the Denver Art Museum by world-renowned architect Daniel Libeskind, the second largest Performing Arts Center in the nation after Lincoln Center in New York City and bustling neighborhoods such as LoDo, filled with art galleries, restaurants, bars and clubs. That is part of the reason why Denver was, in 2006, recognized for the third year in a row as the best city for singles. Denver's neighborhoods also continue their influx of diverse people and businesses while the city's cultural institutions grow and prosper. The city acquired the estate of abstract expressionist painter Clyfford Still in 2004 and built a museum to exhibit his works near the Denver Art Museum. The Denver Museum of Nature and Science holds an aquamarine specimen valued at over $1 million, as well as specimens of the state mineral, rhodochrosite. Every September the Denver Mart, at 451 E. 58th Avenue, hosts a gem and mineral show. The state history museum, History Colorado Center, opened in April 2012. It features hands-on and interactive exhibits, artifacts and programs about Colorado history. It was named in 2013 by True West Magazine as one of the top-ten "must see" history museums in the country. History Colorado's Byers-Evans House Museum and the Molly Brown House are nearby.
