Corrected entry: After Tell Sackett shoots the first Bigelow, he departs Uvalde, which is in Texas, and heads for the hills. He encounters a trapper, and over coffee, they discuss lost gold. The trapper indicates that earlier seekers had perished, some from exposure, some from Crow Indians. However, Santa Fe, where Tell goes to resupply, is over five hundred miles from normal Crow haunts. Far more likely to be Utes, Comanches, or even Apaches.
Corrected entry: During the campaign for election, Tom Sunday's checkered past comes to light, and it is revealed that he served a year in the pen for killing a Senator in New Orleans five years previously. Since the campaign takes place in 1869, that would mean Sunday did his deed during the height of the Civil War, when New Orleans was under martial law. There were no US Senators at the time, since Louisiana was a Confederate State, and since he proved self defense no charges would have been levied.
Correction: It is never said that he was a senator. It says that he was an important man.
Corrected entry: Generally speaking, a crutch is designed to function as a replacement for an injured lower limb, thus being used on the impaired side. However, when Cap takes a rifle bullet through the left kneecap (which, incidentally, would have resulted the the total destruction of the knee), he subsequently hobbles around quite spryly, supporting his undamaged right leg with the crutch.
Correction: As you said yourself - "Generally speaking". This in itself implies that it does not mean all of the time. I have seen many people use a crutch and a cane on the non injured side and lean to that side.
Correction: Tell Sackett does not go to Santa Fe. He goes to Pergatory. Which should be in Colorado. Santa Fe is where Orrin and Tyrell have girls waiting on them and they end up there before the end. The end of the movie/or mini-series is in Pergatory.
