Part 3 - Red Dead Redemption 2 - 1st Playthrough

I have started Chapter 3; the gang has moved to a new, lakeside camp. I have learned to fish, and it is as complicated and realistic as everything else in this game. I really want to learn how to successfully lasso animals like boars and cows. So far my attempts have ended up with me being dragged on my face in the dirt and the animal escaping.
