When young Joe opens the Christmas present from his dad in the beginning of the episode, it is a left handed .22 bolt rifle and young Joe holds it like a left handed shooter would. Later in the episode they show the gun again and it is now a right handed .22 bolt gun and young Joe holds it as a right handed shooter.
When Wacey is asked if they can make it to the elk camp on foot before sundown he holds four fingers up to the sky. This is a way of gauging how many hours it is to sunset. Each finger width the sun is above the horizon equals approx 15 mins.
