Today and tomorrow in Neshoba County, MS is the annual memorial for James Chaney, Michael Schewerner, Andrew Goodman, and all civil rights era racial murder victims. I first attended in 2005. It is an important, meaningful event that is also an opportunity to meet and listen to famous Civil Rights Movement veterans and many unsung heroes of racial justice.
There's an announcement with details posted on the Veterans of the Civil Rights Movement website. Attached is a more recent and detailed press release (PDF) sent to me by the organizers. The event is free and open to the public.
