Heading either East or West on highway 380, the town of Throckmorton (in the county of Throckmorton), the highway patrol officers are ALWAYS in force. I drive this route many times per month, and have yet to see a highway patrol officer with someone pulled over.
The speed limit goes from 65 to 45, and then QUICKLY to 30 while rounding a curve (you see the sign when you enter the curve and don’t have time to react). You will be pulled over if you are not driving EXACTLY (or under) when you hit the signs.

I have driven all over Texas and Oklahoma, and this is by far the worst speed trap of them all.
