Watch the Hunter’s Moon rise majestically over the Seekonk River. Observe the night sky with powerful binoculars. Gaze at the planets through telescopes with R.I.’s amateur astronomers, the Skyscrapers. Hear music that is out of this world: The Crepuscular Cowboys -members of the bands Joe’s Backyard Band and Ghost Cat Rodeo, joining forces- will perform a mix of country, folk, rock and blues, originals and covers by artists like Bonnie Raitt, Johnny Cash, Lucinda Williams, The Rolling Stones, The Band, Bob Dylan, Graham Parsons, Emmylou Harris, and many more! Bring picnics, blankets, family and friends. At Blackstone Field, across from the Narragansett Boat Club (2 River Driver, Providence, RI 02906).
