Tens of thousands of women, a sea of pink hats and glittered signs pulsing with resolve and determination spilled into downtown Denver on Saturday, a massive outpouring for “human rights and equality” the day after the inauguration of President Donald Trump. The women arrived from all directions to gather at Civic Center, so many that thousands stood chanting and cheering in the park more than an hour after the 1.3-mile march began, waiting their turn to walk the packed route.
