Denver is the capital and most populous municipality of Colorado. Denver’s economy is based on its geographic position and its connection to some of the major transportation systems of the country. Large Denver-area employers include Lockheed Martin Corp., United Airlines, Kroger Co. and Xcel Energy, Inc. Culturally, Denver is home to many nationally recognized museums, including the Denver Art Museum, the second largest Performing Arts Center in the nation and bustling neighborhoods such as LoDo, filled with art galleries, restaurants, bars and clubs. Because of its proximity to the mountains and generally sunny weather, Denver has gained a reputation as being a very active, outdoor oriented city. Many Denver residents spend the weekends in the mountains; either skiing in the winter or hiking, climbing, kayaking and camping in the summer.
