Although I tend to agree with the others on writing what you know about, I commend you for atleast trying to get it right by asking.
That being said, I was born and raised in NE Texas and grew up ranching there. I would be happy to answer your questions and help you out as best I can. There are others on this forum I am somewhat envious of because they have a gift of painting pictures with words. I always wished that I could do that, but I'm a better BS'er. If you would like just send me a PM and I will give you my phone number.
Again, I am happy that you are atleast asking instead of writing it blind. When a real cowboy or rancher sees a half-assed attempt about our way of life, it tends to get under our skin. I hope this is'nt a Broke Back Mountain type story. Let me know if you wanna visit. Good luck.
