Canada report # 34
We were driving out to Carter’s parents campground another day. As we were driving I started to think about something seemingly insignificant yet somehow profound: Texas Gates.
I think that whoever invented those was a very brilliant man (or a woman, but I doubt that). It is a simple yet very clever invention. Cows can’t cross it, yet cars can. Can you imagine that there are people who can find solutions to simple things like that? He is probably dead, but his invention is used all over the north America. I wonder was his name Texas or was he from Texas.
P.S. The reason I said that I doubt that woman invented it is not because I think that they are incapable, they most defiantly are. It was more because of the specifics of the invention I tend to see that was more men project. But I might be wrong.

Texas gate - more than you'll ever need to know about them....
A Texas gate, cattle grid or cattle guard, also known as a vehicle pass, is a type of obstacle used to prevent hoofed animals, such as sheep or cows, from passing. It consists of a grid of bars or tubes, usually made of metal, firmly fixed on the ground so that the holes are wide enough for animals legs to fall through, but narrow enough that a vehicle's wheels will not. A cattle grid will allow wheeled vehicles to pass through the entrance, but will contain horses, cattle or other wildlife within the enclosure because they will refuse to step on the gate.
These grids are usually installed over countryside roads where they cross a fence. The alternative is to create a gate that would need to be manually or automatically opened when a vehicle comes. They are common where roads cross open moorland or common land maintained by grazing, but where segregation of fields is impractical, such as in the Scottish Highlands or the National Parks of England and Wales. They are also common throughout the Western United States and Canada, where they are sometimes referred to as a Texas gate. Cattle grids are also used when otherwise unfenced railways cross a fenceline.
While these barriers are usually effective, they can fail due to ingenious animals. Sheep have been known to roll on their backs or sides over grids as wide as 8 feet (2.4m), traversing them in order to find more and better food or water.
Portable texas gates suspend the gate by springs so that it lowers to the ground when a vehicle passes over then returnes to a position 6 inches abouve the ground.
"Virtual" cattle grids can also be used. These look like cattle grids, but are only painted lines on the highway. The light-dark pattern of lines and pavement resembles a true cattle guard to animals. Using a virtual cattle guard is cheaper than a true cattle guard, and can be used on higher-speed roads due to its smooth surface.
