Ask three neighbors what East Haven summer means and you will get three answers that sit within a mile of each other. The Town Green, the sand at Cosey Beach, and the trolley barn on River Street are not separate destinations. They are the same event calendar, staged in three rooms.
That is the argument of this guide. Once you see the season as a single map, planning July and August gets easier, and so does explaining East Haven to the friend who keeps asking why you have not moved somewhere fancier.
