If Texas has always been your dream then, by all means go there. Not that it matters, but from my personal perspective, having hunted Rios in Texas numerous times and Merriam's in the mountain states, I would choose Wyoming,...especially if you are looking for that "classic call 'em in strutting and gobbling" hunt.
You can certainly kill more turkeys in Texas if that is what matters to you, but if aesthetics are important, Wyoming would likely be a better choice,...at least for me based on my experience.
Either way,...good luck!
