Southern Pride?

Went to the the Robert E. Lee Chapel and museum in Lexington, Va. last week. His horse, Traveler (who died of lockjaw) is buried outside. Patrons (mostly southerners) leaving the museum throw pennies on top of the horse's grave.

I don't know about you, but I'm fairly sure Lee would not have appreciated people tossing portraits of Lincoln on Traveler's grave.
