Dr. Ride’s American Beach House, a new play by Liza Birkenmeier, is an intriguing slice of life set on a St. Louis rooftop on Friday, June 23, 1983, the night before Sally Ride became the first American woman in space. If younger members of today’s LGBTQ community often take for granted the plight of their elders, Birkenmeier’s play bravely imagines what it was like when being gay involved claustrophobic secrets, blind struggle and a stepping into the void to create a reality without social or cultural precedence.
