Thanks Andrew.
I was thinking about coming back to this thread to explain that part of it. You did a good job.

Not only is "Out of Bounds" not prohibited, "closed for the season" in parks just means no services. Going into the park outside of season is not a criminal offense either

You need to do the notification thing like Russ, Comms, DesertFox and others say, just like if you were heading into the north bush.

Now accepting that they didn't cover that need properly, knowing that their SOS was basically ignored even after it was reported should still give you a bit of a pause.

What if a person was in there and had never been at the lodge? What if it had been somebody else whose life was lost based on the resort's front desk flunky not finding a car in the parking lot (that they were too incompetent to even properly check)?
What if SAR or Coast Guard decided they needed a missing persons report before responding to a PLB, SOS broadcast or red flares?
What if they were depending on hotel parking staff for that report?
