In the last two weeks of the year, there would be the Aspen Historical Society cookie exchange and Aspen Santa Fe Ballet’s “The Nutcracker” and Aspen Film’s Academy Screenings, the Theatre Aspen Cabaret Series and JAS Café concerts, a premier nightly lineup at Belly Up Aspen, galas and parties like the Aspen Art Museum’s “The Next” and the family-friendly happening of the 12 Days of Aspen. Not this year, as the novel coronavirus pandemic continues into 2021.
