End of August through Labor Day
Official state agricultural and industrial fairs started in the United States in the middle of the nineteenth century. The Colorado Agricultural Society held the territory’s first agricultural fair northwest of Denver in September 1866, featuring a half-mile racetrack as well as displays of large vegetables and prize livestock. Over the next two years, the fair expanded to include more agricultural exhibits as well as examples from the territory’s mining industry.
Third weekend after Labor Day
In some places, the sight of falling leaves is synonymous with fall. In Pueblo, the savory aroma of roasting chilies signals summer’s end. Every year, thousands pay homage to Pueblo’s best-loved crop: green chilies, particularly Pueblo Chile. The event features live entertainment, street vendors, cooking competitions, and chilies, chilies, chilies! Held downtown along Union Avenue, the festival draws Pueblo residents as well as people from across the state and around the nation.
