Quonset, specifically where Lowe's used to be by the rotary, and NEIT's EG campus are the ones that come to mind first, East Greenwich High School has a big campus too with a lot of roads and parking lots that aren't super crowded when school isn't in session, especially during the winter. I know people would go to the Veteran's Cemetery in Exeter and St Joseph's Cemetery in WG too but if you do that try to go to the areas that are less developed to be respectful to families visiting.
