Next week on The Exchange, we begin with the question of government’s role in fighting obesity, given the recent challenge to New York City’s super-size-soda ban. Then, we sit down with Mark Huddleston, President of the University of New Hampshire. And on Friday, a new tradition in the making on “The Exchange”, our weekly news roundup where we look at the issues Granite Staters are talking about. E-mail us at NHPR dot org and join us all next week for the Exchange, every morning live at 9/and again at 8 p m....here on NHPR!
