Sounds like it might be a nice time on Saturday.
The march starts at Emery Rec Center at Georgia and Madison at 10:30 am, then goes down Georgia ending at the African-American Civil War Memorial at 10th and U. I assume you can join up along the way.
I don't know much else about it than what's on their Facebook, but presumably it's in response to Donald Trump's divisive rhetoric.
BloomBars is also hosting a sign-making event on Friday.
Here's the Facebook invite and more from the organizers:
Join us on Saturday, March 11th as we march and celebrate with local artists, musicians and community members to celebrate our diverse neighborhoods. Featuring musical acts Elena y Los Fulanos, Lilo, Ethiopian Dance and many more!
The Love March seeks to support diversity and inclusion in our community. We will march on Saturday March 11th not downtown, but right through some of DC's most diverse communities along Georgia Ave. NW starting at Georgia and Madison St. NW at the Emery Rec. Center and marching down to U St ending at the African-American Civil War Memorial Site.
We will be making pledges to support local, small, especially minority owned businesses, connecting to local organization who already work to support diversity and inclusion in our communities and discussing the important work ahead to maintain diversity as a source of stregnth in D.C. and how we can make it clear to all of our neighbors that "whoever you are, wherever you're from, we stand together as neighbors."
