This week, we talk to Leo Karl III, past president and longtime member of the New Canaan Rotary Club, about the organization’s Lobsterfest. An important fundraiser that benefits local nonprofit organizations, this year’s event runs Oct. 15 and 16, and includes some new “dine-in” options for those seeking a fresh lobster, salmon or fried chicken dinner, as well as the ability to purchase meals for New Canaan’s emergency responders.
