I'm not a local but I tried! I mapped Aubree's route, New Fork Lakes to Dubois, and Jose's route, Riverton to the landfill on Sand Draw which is about 10 miles southeast of downtown Riverton on Highway 135.
Here's a screenshot of a map of Aubree's route. The top black arrow points at Riverton, where Jose started, and the bottom black arrow points to the approximate location of the landfill, which was his destination (but he didn't arrive). As you can see, Aubree's area and Jose's area are near-ish to each other but it's not the same highway. Hope that helps!
