0517z 128.200 Hearing Boston Center (ZBW) controller working HIPPY 77. ZBW told 77 to go direct MANTA-DRIFT-COYLE-McGuire. I have not heard 77 as of yet. At night, the local controller works several frequencies and I can't always hear the planes on the fringe of his transmitters. I'll update if more heard. Ed Langworthy Gray, ME
