Texas, in addition to what we know from the Dallas TV show, is the second largest region in the United States, after Alaska. This state has nearly 30 million inhabitants and plays a major part in the country's politics, with 3 past Texan presidents.
Having lived there for 3 years, we can say that the Texans are very nice people and they will always be inclined to invite you to their home. On the other hand, even if they know the image they inspire, they are very attached to it. Make no mistake about it: their country, their state, their guns is their pride and they will always let you know about it.
