BMoCA's venture into community involvement, Museum of Broken Relationships, is actually the local incarnation of an international movement based in Zagreb, where former lovers Draen Grubiic and Olinka Vitica curate a permanent collection of cast-off mementos left behind when relationships end. Boulderites and other Front Rangers answered BMoCA's call by donating their own relics of love lost for the exhibit, which is on view through May; after the show ends, the keepsakes will make their way to Croatia for a symbolic eternity in the brick-and mortar Museum of Broken Relationships.
