This article reports on a New Hampshire proposal: whttp://www.concordmonitor.com/time-zone-Atlantic-bill-7545169 http://www.concordmonitor.com/time-zone-Atlantic-bill-754516... And this one on a Rhode Island proposal: https://www.bostonglobe.com/metro/2016/03/11/will-new-england-secede-from-eastern-standard-time/4T9tNuLYXX3rz3SKWMpkZI/story.html https://www.bostonglobe.com/metro/2016/03/11/will-new-englan... Both explicitly require Massachusetts to go first. Maine has been considering it for longer (which makes sense, as it's further east), since 2005, according to this story: https://bangordailynews.com/2017/01/19/politics/state-house/maine-lawmakers-take-another-stab-at-changing-states-time-zone/?ref=topStories3Thumb https://bangordailynews.com/2017/01/19/politics/state-house/... . The proposals there don't seem to be contingent on Massachusetts making the first move. I couldn't find any references to proposals in Vermont or Connecticut.
