High school senior Megan Bickford, 17, dances at her prom in Harrison, Maine, U.S., May 15, 2021. Prom was held outdoors under tents, with students wearing masks. Bickford, who was raised in a liberal family, said she grew increasingly alarmed when she saw Confederate flags pop up on porches or vehicles northwest of Portland, where she and her family live. "I feel like if we had a more normal four years I probably wouldn't be as loud," she said. "I'm growing up in that political climate where it seems like if you don't scream, the other side won't hear you." REUTERS/Brian Snyder SEARCH "CLASS OF 2021" FOR THIS STORY.
