Throughout Pres. Clinton’s summer vacation, he’ll be followed by radio and print ads urging him to permanently ban road-building on up to 60 million acres of wild roadless national forest land. A $100,000 media blitz by the Heritage Forests Campaign will pay for 180 radio spots in Massachusetts, hoping to catch Clinton’s ear while he relaxes on Cape Cod and Martha’s Vineyard. The enviros have also purchased full-page ad space in Cape Cod newspapers and publications in Long Island and New York’s Finger Lakes region, where the Clintons plan to visit. And the group will air radio ads in Washington, D.C., timed for Clinton’s return to the White House next month.
