I came upon MapDust bug 209335, http://www.mapdust.com/detail/209335, which noted some misplaced and missing streets. Further review of satellite imagery showed that there was a massive issue in this area where the Tiger data was missing lots of streets, and the streets it did have where grossly misplaced and mis-shaped. The problem only seemed to exist on Pleasent Hill Road north of Southport Road and South of John Young Parkway, but that area is pretty large.
Anyhow, after many hours of fixing, redrawing, and adding roads, I was finally able to close out the bug today.
After the hiatus of squashing a bunch of MapDust bugs, and marking many more invalid, I'm back to mapping out my homeland. I've already fixed up a bunch of roads, and added others. Soon I will need to do some on-the-ground checking to get some road names and find out what's going on with roads that, from the aerial imagery, don't seem to actually exist.
