The Rig in Camden was established by older teens as place to "hang art, make music, talk about things that matter, sometimes with adults, sometimes not." A grant from the community foundation’s Knox County Fund helped launch the space. The fund is marking its 20th anniversary of grantmaking this year. In honor of the anniversary, an anonymous donor has offered a $20,000 challenge grant to help build the fund. Photo courtesy of Penobscot Bay Pilo
