Sunday marked the 46th annual Pride March in Manhattan, and this year's festivities took on a different meaning for many following Friday's historic Supreme Court ruling, which legalized same-sex marriage nationwide. Tara Lynn Wagner filed the following report.

A wet morning gave way to thousands of rainbows as the 46th annual NYC Pride March made its way down Fifth Avenue. Not that anything could have dampened the spirits here.

"To celebrate humanity and love and happiness and everything. I'm just so happy," said one march attendee.

With more than 20,000 participants, this is the largest turnout for the event. It's also the most historic, coming days after a Supreme Court decision that legalized same-sex marriage throughout the United States.

"I think the Supreme Court decision is amazing, and I never thought I would see it in my lifetime," said one march attendee.

"I mean, I thought it would happen eventually, but I didn't think it would happen for a long time," said another.

"We hoped it, we dreamt about it. But we just didn't think it would happen, and it did," said a third.

Among the spectators were people who have never been to pride and folks who've been coming for decades, all of whom said this is a celebration they couldn't miss.

"It's so exciting," said one march attendee. "I felt like I had to be part of history today."

"I've never been before, and a lot of my friends are part of the LGBT community, and I just wanted to be here to support them," said another.

"We're making incredible strides, and it's great to be part of the history, and it's great to see it in my lifetime," said a third.

As much as it's a celebration, organizers say it's not a parade. It's a march. And they say even with the recent victory, there's still work to be done. Which is why in addition to actors Sir Ian McKellen and Sir Derek Jacobi, they chose activist Kasha Jacqueline Nabagesera of Uganda as a grand marshal.

"You give us hope. You fought so hard to be where you are today," Nabagesera said.

For some, the fight ends with them dancing down the aisle.

"We're heading to City Hall right after this," said one march attendee.

But others took a moment to simply celebrate what they see as the bigger picture.

"It's not just about gay people being able to get married, but that gay people are actually on the same playing field as their straight friends," said one march attendee.

And that's music to their ears.
