Claressa “T-Rex” Shields rose from impoverished Flint, Michigan, to a place in Olympic history, becoming the first American woman to win a gold medal in boxing in London in 2012. The Library and KCPT-TV screen the documentary T-Rex (2015; NR), which chronicles her inspiring, against-the-odds story as part of the Indie Lens Pop-Up community cinema initiative. Afterward, Kansas City, Missouri, Parks and Recreation and KC Golden Gloves share some of the tips and tricks of boxing during a special demonstration.
