Realistically, I'd get the hell out of Texas. The fact that we've had drought conditions that may last for a few years isn't a good situation. Seclusion isn't always the best bet, but for a small period of time that would be best. The initial shock and panic alone would probably be the tough part. Not knowing what the other millions of people had on their agenda would be the first threat. Strength in numbers would be an ideal situation, so it makes you dig deep as to who you could really trust. I'm glad I've got a little experience in the woods, along with hunting and what not. The tough part would be getting back to those primal instincts and sharpening those skills.
I'll be honest to say I'm not 100% prepared, and I don't think most Americans are. A running joke of preparing for zombies, corollates to any SHTF scenario. I'm hoping to be 100% with in the next few months.
