tay away from Muncho Lake, BC

Got my butt chewed there one time. I had fueled up and pulled across the highway to park, and eat lunch in the camper. We had a Tahoe pulling a small travel trailer at the time. I'm parked next to a huge box truck with several men unloading it. A guy walks up and unpleasantly tells me to move, since I parked on a runway. "Runway" as in no signage, and nothing but another gravel pit looking barren spot on the edge of the highway. I motion to the box truck, which apparently is not an issue, and the guy says, "move it" and walks away. Now if I did accidentally park on an unmarked runway that looked suspiciously like a gravel truck parking lot, complete with truck, I have no issue with moving immediately. However, being a jerk wasn't a requirement.
