"The jog compensates for the curvature of the earth."
LOL
Sure, any country boy knew that by the time he was 10.
"The jog compensates for the curvature of the earth."
I probably should explain a little.
If you put squares on a globe, the corners won't match with the next square 'above' it. That's because the distance around the globe becomes smaller as you reach the poles. That same situation causes problems with lining up county roads.
I grew up in southern MN, the N/S roads to the north of our house jogged about a hundred yards in order to meet up with the roads in the next county. Nearly every N/S road did so.
Texas is closer to the equator, and the jog for the same size county won't be a large, but the counties are probably larger
