This week, we talk to New Canaan High School junior Oliver Tuff, founder and president of Feeding 500. Since its founding last year, Feeding 500 has drawn dozens of NCHS and Darien High School students who raise money for the food program at Open Doors in Norwalk. Upcoming events that the organization is supporting include food drives at NCHS and Walter Stewart’s Market starting this month, and at the Nov. 21 Turkey Trot.
