I grew up in Miamisburg Ohio during the 60-70's era. I attended public schools which at the time were 100 % white. I can remember being shocked by seeing the 1st black bag boy employed by the local Kroger grocery store. The posted sundown signs were before my time. But i remember my older brother inlaw talking about where they were posted on a bridge & city limits. Does anyone have a pic of one ? Or remember the wording of the ones in your town ?
