I am about to ask a simple question. It is not a trick question, so no reason to over-think it. The map below (like most maps) is oriented with north at the top. You might not be able to make out much detail, but that's ok, because all I want you to do is take a look at the highway shown in blue. And the question is simply this: does this highway run north-south? Or does it run east-west?

US 87 and US 287 converge in Dumas, Texas, and share about 49 miles of pavement down to Amarillo, where the two routes separate again.
