Band together with neighbors, there is strength in numbers. Hunker down, don't draw attention to yourselves. Maybe that would work, maybe not.
There is a member on TEG that was a child in WW2. He and his family lived in the woods for 2 years, hiding from the German soldiers. He doesn't talk much about it, but every now and then a sentence or two slips out. He was hiding in a wood pile and saw soldiers haul a farmer and his wife outside and shoot them both. They survived starvation, snow and cold and running for their lives.
So you would need to be able to run, leaving "things" behind. Grab your family, what you could carry and hide.
My hope would be that Texas would form her own country again but it would be won by blood.
