North to south.

Unless New Mexico is pursuing different land from Texas, this was settled in court a few years ago in Texas' favor. I don't remember the date but it was in the local Fort Worth Star-Telegram.

Hope I can articulate where they are talking about. Notice there is a tiny strip of land belonging to New Mexico just north of the Texas panhandle? New Mexico was saying all the Texas land BELOW that strip belongs to them which includes towns Texline, Farwell & ghosttown of Glenrio. Local residents prefer to stay Texan. The NM-OK-TX tri-state corner would still remain a tri-state corner-just a different configuration
