Next week on The Exchange, we bring you some of our favorite Exchange shows of the past year. We begin with the question “Should government play a role in our growing obesity problem” from nutritional labeling to super size sodas. We also look at New Hampshire downtowns, where they’re doing well and where they aren’t. We talk to former Shell Oil President John Hoffmeister on his ideas about the future of energy. For Independence Day, we bring you our program on Calvin Coolidge, a President born on the 4th of July and we end the week talking about the bullying problem in NH.
