So, how does GeoBase go about determining where the roads are?
I happened to find something interesting in the GeoBase data.
There's a little jog in Township Road 520. This is not a real world
artifact. This road is just about arrow straight through there.

There's another smaller jog in Township Road 522 two miles north.

The interesting part is when you go into edit mode. These anomalies
occur right where the Yahoo Imagery ends. Coincidence?
