Couples boarded buses during rallies Monday in Indianapolis, Milwaukee and other cities, saying they believe they're on the right side of history.
The 7th U.S. Circuit Court of Appeals in Chicago is scheduled to hear oral arguments Tuesday in a combined appeal from the states. Gay marriages bans in both states were ruled unconstitutional in June.
In Indianapolis, Henry Greene and his partner of 23 years, Glenn Funkhouser, were among about 100 supporters at a send-off rally. Greene says he's confident gay marriage will eventually be legal nationwide.
In Milwaukee, supporters blew bubbles and held up signs as same-sex couples and others boarded a Chicago-bound bus.
