If the 700 block of North Robert A. Stalls Street is in the northeast section of town, then WRPT, I concluded after having read it.
Northeast Carbondale, anywhere east of Route 51 (Illinois Avenue) and north of Route 13 (Main Street), is Bell Curve City.
Another hint is that this happened very close to a city park named Attucks. As in Crispus Attucks.
Even though I don’t know this for sure, Robert Stalls was probably some prominent black preacher.
