On this week's Around the Triangle, we'll learn more about the work of The Scrap Exchange in Durham. They have a Sustainability Expo next weekend; details at http://www.scrapexchange.org/. We'll also speak with the operator of a local Jersey Mike's franchise about their 'Month of Giving' initiative underway now. They're raising money to benefit a local non-profit called Military Missions in Action. Learn more at http://www.militarymissionsinaction.org/.
