I have seen and heard them at our place in Lee County, right along the Yegua Creek. My sister and I heard one scream after getting home from a dance one night. She and I met at the back door, I was running in and she was coming out... Scared the crap out of both of us. We each thought it was the other screaming, but we soon found that wasn't the case. The next morning my dad found big cat prints right in the yard. He used to see them while out hunting in the creek bottom, as well, which borders Burleson County. I can't imagine why they wouldn't be in Brazos County.
