At the stroke of midnight on May 1st, civil unions will be legal in this state. First, what are civil unions, and how do they differ from marriage -- which Colorado voters have defined as being between a man and a woman? Ryan Warner put those questions to Denver attorney Kim Willoughby, author of a legal guide for gay and lesbian couples in Colorado. Then, CPR's Andrea Dukakis speaks with Gena Hendrix and Crea Fusco. The two already had a wedding ceremony, but they're planning to have a civil union this month.
