At the Council of Unitarian Universalist Camps and Conferences homepage you can see 29 camps and conferences listed, with pictures, along with a link to each. It’s a great jumping-off point if you are looking to do something “UU” this summer. Although many conferences are meeting virtually, a number of dedicated UU spaces are available for socially-distanced and family outings. Check out the website at cu2c2.org.
Two conferences popular with Heritage UU people are the Midwest Unitarian Universalist Summer Assembly (MUUSA) and the Southeast Unitarian Universalist Summer Institute (SUUSI). Both are meeting virtually this year. You can learn more at muusa.org and suusi.org.
