Next week on the Exchange– We begin looking at our state's Great Bay region. Pollution is taking over and communities, activists and officials can't agree how best to eradicate it. Then we sit down with one of the biggest players in New Hampshire politics this year, Republican House Speaker Bill O’Brien, on what he feels his party accomplished, and some of the session’s controversies. Then the following day, House Democratic Leader Terri Norelli joins us. Later in the week, we kick off our coverage of the New Hampshire Gubernatorial Primary…with Democrat Maggie Hassan and we discuss the debate around prison privatization. Email us at nhpr.org and join us all next week for the Exchange each morning at 9/and again at 8 pm...here on NHPR!
