It's peaceful at San Francisco's Civic Center Plaza despite large gatherings of very vocal protesters on both sides of the gay marriage debate.
Big signs which say "Traditional Marriage" stand alongside ones that say "No on Hate."
Some of the most passionate here stood in line as early as 5 a.m. to get a seat inside the Supreme Court chambers.
One gay couple drove through the night from Los Angeles for a chance to be inside.
Once the arguments began, hundreds gathered in front of a Jumbotron screen on the plaza to watch and listen.
Cheers would go up periodically depending on the points being made by the lawyers.
Jusices peppered the attorneys with questions.
One lawyer arguing against Prop 8 said voters may not amend the constitution to descriminate against a minority group.
But at least one justice argued that California's unique constitution, more than that of any other state, gives broad power to the people to change it if they so desire.
A decision is expected within 90 days.
