I have live in Dallas TX, the place i would go is Ft. Davis or maybe Alpine TX. Both of those places are in Southwest TX not from the Mexican border and don't seem to be in or near any target list. I know the area very well having spent a lot of time in Marfa and Marathon ( i was married in Marathon ).

The fallout maps are kind of all over the place, you can GIS for us nuclear fallout map but below is a link to a simulation that is in alignment with the rest of the maps more or less. Granted, local weather makes a huge difference so take that into account.

The signal in my mind is a NATO soldier killing a Russian soldier. I wfh so if that happens i go work from Alpine TX for a week and see if there's an escalation. If not, i come back and buy a round of drinks for my friends for being a paranoid nutjob.

Granted, it's not that simple. I have a wife+2kids and MIL in a garage apartment. what about them? Also, we have 5 pets between us. Do i hire a pet sitter? heh it's ridiculous to contemplate to the point of being offensive to those with artillery raining down on them right at this moment. But given the brain i'm blessed/cursed with, thinking through these things is how i cope.

edit: i want to reiterate this.

i wrote my post over a nice hot cup of coffee while sitting in my home office waiting for a conference call to start. I can never know the fear and anxiety affecting those in a very real line of fire. I just want to point out that i realize that.
