Every January, the National Western Stock Show is a huge rodeo and stock extravaganza for wranglers. Native American powwows, including a big gathering in late March, take place annually in Denver. Then there are all the funky mountain towns, each with its unique microculture.
Colorado is the king of scenic outdoor venues and enthusiastic, high-altitude fans, so it attracts phenomenal musical acts from around the world, especially in the summer. Red Rocks Amphitheater, just a couple of miles west of Denver, is one of the best places to see a show, anywhere; it's one of the world’s few naturally-occurring acoustic amphitheaters. Telluride Bluegrass Festival, high in the San Juan Mountains, is legendary. And scores of smaller music and food fests are scheduled throughout the spring, summer, and fall. Many towns and cities have developed annual customs like the International Snow Sculpture Championships and Ullr Fest in Breckenridge, and mid-April sees the Cannabis Cup in Denver.
