The TIGER data in York County, PA was horrific. York City and Lebanon were completed some time ago. Just completed Red Lion, Dallastown and Yoe (that's a real place). Back in Maryland, bad early TIGER data is found in Anne Arundel, Garrett and Queen Anne's Counties.

Boy, I hate how bad the TIGER data is!! It's also super old, too.

Only thing it gets right is the relation of the streets to each other, just enough for Census workers to canvass an area. As if I drew a diagram on a piece of paper. So, you'll know the name of the third street on the right, and it has a street looping off it to the north and that street's name too, but it's nowhere near the exact position in real life.
