An intimate look at one of culture's most enduring taboos: public sex. Park Cruising takes a long look at the men who cruise for sex in urban parks. Human rights lawyer Marcus McCann uses park cruising as a point of departure for discussions of consent, empathy, public health, municipal planning, and our relationship to strangers. Prompted by his work opposing a police sting in a suburban park, McCann's ruminations go beyond targeted enforcement and police indifference to violence to examine cruising as a type of world-building. The result is a series of insightful and poetic walks through history, law, literature, and popular representations of cruising in search of the social value of sex. What McCann ultimately reveals is a world of connection, care, and unexpected lessons about the value of pleasure.
