As the kids and Murphy are coming into town to spend their 10 cent pieces, you can see Lizette looking over Murphy's shoulder. When the camera switches to up close on the wagon, she is now on his left shoulder.
In the opening camping scene, Will is pulling on the rope to anchor the tent above. Note his location is nowhere near any trees/bushes. Note beyond the camp, there are no small trees like firs. When Murphy asks Archibald about helping, you can see Ephram at the back of the wagon, and there are no small trees behind them, just a road. After Murphy yells at Archibold to unroll the bedrolls now, the scene switches to looking at the wagon from the side, and Will and Ephram walking toward Murphy with fishing poles. The road and clearing behind the wagon is gone, now there are small firs and trees. The wagon sits right up against these trees now. The right side rope appears to go into bushes. This is a different location.
