On Friday, June 20, from sunrise (4:59 a.m.) to sunset (8:26 p.m.), Preble Street Homeless Voices for Justice will sit out in Post Office Park to mark the seventh annual Longest Day of Homelessness Summer Solstice Vigil, the organization reported.

Homeless Voices for Justice advocates will be joined by other organizations and community members, "sitting out in solidarity to show support for those who experience homelessness, to highlight the causes and circumstances of homelessness, and to discuss what needs to be done to end homelessness.

Anyone interested in participating in the sit-out is welcome to join for five minutes, for an hour, or for the whole day," a press release reported.

Preble Street Homeless Voices for Justice is a grassroots group that works for social change on behalf of people who struggle with homelessness and poverty. HVJ is led by a board of people who have all experienced homelessness and is supported by Preble Street staff. The founding chapter in Portland has existed since 1995, with other chapters started in Alfred/York County, Augusta, Brunswick and Lewiston.
