Jessica Catto Dialogue | Michael Curtin

Michael Curtin, CEO of DC Central Kitchen (DCCK), will present a free Jessica Catto Dialogue lecture on August 9th at Paepcke Auditorium in Aspen. 

DC Central Kitchen is America's leader in rebuilding urban food systems through social enterprise programs such as training unemployed adults for culinary careers, reducing hunger with recycled food, and preparing and serving healthy school meals.

When Mike joined DCCK in 2004, he drew on his experiences as an entrepreneur in the restaurant business to fund and launch DCCK’s Nutrition Lab Facility and expand the Kitchen’s social enterprise portfolio from a small catering outfit to include a full-service catering, contract meals, locally-sourced, scratched-cooked school meals, and a wholesale program that delivers fresh produce and healthy snacks to corner stores in Washington DC’s food deserts. As a result of DCCK’s growth under Mike’s leadership, the Kitchen now employs over 150 people, including 60 graduates of the Kitchen’s nationally recognized Culinary Job Training Program, which trains formerly incarcerated, addicted, homeless or chronically unemployed individuals. 

Mike lives with his wife, Maureen, and their three children, Maeve, Michael III and Ciara, in Falls Church, VA.

Please walk, bike, bus, or carpool to Paepcke Auditorium as parking is very limited. RSVP does not reserve a seat.

Aspen Spring Migration Bird Count

Calling all interested Roaring Fork valley birders to join us for part or all of this citizen science count to record birds in the Aspen area during spring migration. ACES Naturalist Programs DIrector Jim Kravitz, Forest Programs Director Jamie Werner, and bird guide Rebecca Weiss will lead the census explore Hallam Lake, North Star Nature Preserve, and other locations to record sightings of a variety of both migratory and resident birds. The data we record will help monitor trends in avian populations, both locally at Hallam Lake through ACES' phenology studies, and also through eBird, a project of the Cornell Lab of Ornithology and the National Audubon Society.

5:15am – 6:30am: The first segment of the count is an hour-long census at Hallam Lake. Please arrive at ACES' visitor center by 5:15am and enjoy coffee and muffins as we explain how to record the birds we see before spending an hour observing birds throughout the preserve, wrapping up at 6:30am. 

6:45am – Noon: The second segment will follow directly afterward, beginning at 6:45am at ACES' visitor center. We will gather our clipboard and scope, and head out to survey the diverse habitats around Aspen where we will see an array of exciting birds. We will carpool for this portion of the count, concluding at noon at ACES.

Please dress in warm layers with sturdy footwear, and bring hat, sunblock, and snacks. Bring your own binoculars or borrow a pair from ACES.

Toklat Book Club | March

The Toklat Book Club will aim to read approximately one book a month and gather for a fireside, evening discussion. We will select literary works, including novels, essays, biographies, poetry, and more, that connect to nature in some way.

Our second book is Zen & the Art of Motorcycle Maintenance: "One of the most important & influential books written in the past half-century, Robert M. Pirsig's Zen & the Art of Motorcycle Maintenance is a powerfully moving & penetrating examination of how we live, a breathtaking meditation on how to live better. Here is the book that transformed a generation, an unforgettable narration of a summer motorcycle trip across America's Northwest, undertaken by a father & his young son. A story of love & fear--of growth, discovery & acceptance--that becomes a profound personal & philosophical odyssey into life's fundamental questions, this uniquely exhilarating modern classic is both touching & transcendent, resonant with the myriad confusions of existence & the small, essential triumphs that propel us forward." 

Book club participants are expected to read the book before the group discussion, held at 6pm on Wednesday, March 30th. 

Light refreshments provided.
This is a free program, donations welcome.

Please RSVP below.
