Or... you could buy a life! :nerd: 		Greg (193)
521283 2007-01-31 22:54:00 I don't know much about anything/anyone from USA, but for some reason I like Texas . Probably has to do with that fantastic TV series Lonesome Dove .

I love that series too . . . even have it on a commercially recorded DVD set . It centered on the characters of Gus and Cap'in . . . . er . . . . . (forget his name here) . . . they were ex-Texas Rangers . For the most part, it was very accurate and indicative of the era and the locale .

Just be sure to see "Little Big Man" with Dustin Hoffman and "Dances With Wolves" to get a better balance .

Here's something you might not've known:

The Texas rangers were actually a bunch of thugs with badges .

Their lethal commission by the governor of Texas was for the purposes of forcing the Mexicans out of the Spanish land grants that were in perpetuity owned by them . They used skulduggery and menaced the occupants with taxations that were illegal by the original deeds .

The fact that the Texas Rangers were all (to a man) also land owners in Texas and they wanted to rid the area of Mexicans, given the legal license to assassinate and murder those who resisted being thrown out of their legal land, makes the presentation of them per Hollywood's standards and penchant to re-write history totally wanton and putrid .

"Special" badges . . remember the scene in "Treasure of the Sierra Madre" with Bogart where the Mexicans answered . , "We ain't got no stinking badges!" . . . ?

Well, that was more true than fiction . The Mexicans had notices posted on the courthouse doors that told them in English that they owed a small property tax . . . and since they didn't go near the courthouses nor did they read English, they were tax sold out from under them . . . and this is where the Rangers came in .

They were the enforcers of the tax sales and could shoot and kill at will any and all the Mexicans who resisted . Some even were shot in the back repeatedly when they walked away from their haciendas . . . but obviously not fast enough .

The Eagles had a recording of the song from that era . . . "Desperado", which is an old Mexican song of the plight of the people who were illegally displaced . Some of the words were changed to make it more or less neutral in content .

Texas has a very bloody history . . and people forget that the US has been the big gorilla in the room for a long time . . . since the Barbary Pirates days anyway and the advent of the Leathernecks .

Texas is where the current big gorilla lives . 		SurferJoe46 (51)
