Question: Are those ski trails on the mountains at the beginning of True Grit?
Answer: The mountain in the background appears to have two vertical grooves down the surface facing the camera. Those grooves are far too wide to be ski trails. They are simply a natural part of the mountain. Mountains are subjected, over hundreds of thousands of years, to a variety of natural forces, such as wind erosion, water erosion, tectonic shifts and earthquakes, just to name a few. These cause mountains to have irregular shapes, and irregular surfaces.
Question: When George is killed by the hoodlums in the middle of the night one of them appears to be wearing a hat similar to the one worn previously by the prejudice guy in the restaurant. Are they supposed to be one and the same?
Answer: Correct: it is the same group of bigots, who has tracked them down in order to beat them.
Answer: Coconut.
No, we see them trying to break the coconut (and failed miserably) after Ratso made that dish (and it looks like some kind of stew, probably made from the tomato we saw them steal at the same time they stole the coconut, and green peppers).
