Planned Parenthood supporters started the New York Women's March. But banners, barricades, and uniformed police melted away as up to 600,000 took part. An ever-surging tide of marchers overflowed the official route and washed onto sidewalks, side streets, and scaffolding. There were too many protesters to contain, with thousands--wheelchair-bound, children, sidelined claustrophobes--impossible to see and count.

Attention-grabbing signage was everywhere.

#ToddlerTrump never broke character as he mewled or crawled across 42nd Street.

The thousands of kids in the parade were hard to see until parents got clear passage to the sidewalks to give them a break.

The Women's March was scheduled to start 11am near the UN. From 10am on, protesters had to fight their way out of Grand Central's main hall, due to the volume of marchers already in the streets. The train station became a refuge through the day.

In the home stretch of the march near Fifth Avenue at Trump Tower: the very young hung on--as long as their parents did.

A reference to the new president's hair color and a TV series about a women's prison...

One of the many choke points, on 42nd St. near Grand Central. Protestors overran the official barricades to march on sidewalks and under scaffolding.

Young women banded in pairs and groups to get out their Women's March messages.

Millennials had a lot to say to the new president.

Women of all ages, backgrounds, and professions vigorously shook signs and chanted.

Young women riding the subway to the protest early in the morning were already in march mode.

Throughout the day the great hall of GCT acted as an auxiliary protest location.

This "Meter Maid" wore a hand-made shield showing her march message, "Violation!", and new renderings of old New York parking meters.

The crowd continued to swell in the march's last hours. Here, protesters of every stripe, including a woman cradling a baby, march up Fifth Ave on the approach to Trump Tower.

Amid the ranks of Planned Parenthood marchers, supporters carried their own messages.
