Groups on both sides of the debate plan to show up at Gettysburg National Military Park for Confederate Flag Day.
The Sons of Confederate Veterans have plans to honor the stars-and-bars battle flag that some view as divisive or racist.
And Scott Hancock, a professor of history and Africana studies at Gettysburg College, says he's gotten a permit to hold a counter-demonstration at the battlefield's Eternal Light Peace Memorial.
The Sons of Confederate Veterans, based in Columbia, Tennessee, say the flag is simply part of American culture.
Hancock says the group is guilty of "miseducation that revises, narrows and sanitizes the long history of that flag."
The event is scheduled from 2 p.m. to 4 p.m. Saturday.
