The Potbelly Perspective series features valley residents and visitors who share stories of their world travels and adventure trips with the public. Sponsored by the Aspen Center for Environmental Studies (ACES), these events take place at the ACES center at Hallam Lake. Tonight's presentation is Antactica: Vinson Massif Ski Exploration and will give attendees a sense of the extreme cold and remote conditions experienced by Penn Newhard and friends as they explored part of this remote, pristine continent. The lecture begins at 7pm. Details at www.aspennature.org.
