Here's a good event for drawing you out to West Texas...

Rich,
If you come out for this, you're welcome to ride with me road hunting.
I may also be going out on Memorial Day weekend.
As mentioned, you will need a hunting license, a herp stamp, and a reflective vest.
Getting out and walking the cuts with a good flashlight or headlamp is what I typically do.
