On Saturday, August 17 at 2 p.m. University of Vermont cultural anthropologist Luis Vivanco will give a presentation at Cold Hollow Sculpture Park in Enosburg, Vt. Vivanco's work weaves unlikely connections between history, comics, and ethnographic research on bicycles and his talk at CHSP will reflect on the meanings and importance of playfulness in interpreting our present through the past.   Vivanco is co-director of UVM’s Humanities Center and recently authored the Dictionary of Cultural Anthropology, published by Oxford University Press.   The Cold Hollow Sculpture Park includes over 60 sculptures spanning five decades by artist David Stromeyer--programming explores the intersection of intellectual and creative pursuits.   The indoor presentation will be followed by light refreshments and conversation with Luis. Free and open to the public.
