Yes, it was Grimes County, Texas between Keith and Iola. Since his property is wooded, as is the back of my property, it fits 12f's description. You might say that my neighbor had a lot of experience handling the two legged variety of venomous snakes, but I do not know if he has experience handing the legless kind. He is one of the few neighbors who does not kill every snake he sees.
Several years ago another neighbor had mentioned running over an eight foot timber rattler on the road, but I always took what he said with a grain of salt. At the time I interpreted an eight foot long rattle snake to be a four foot rat snake. Maybe he actually did see a timber rattler.
