[pct-l] Circumstances that warrant hitting the SPOT 911 button

[Len Glassner]

Generalized criteria?

It almost seems that if you still have the presence of mind to use
911, then you're not in bad enough shape.

I guess if you're unable to move (i.e., broken leg), then?  And have
also fallen off the trail?  Or do you blow your whistle and wait for
other hikers to come along for xx hours, and reevaluate?

If you're really hypothermic, then SPOT won't occur to you.

Lost for xx days?

Use only for other disabled hikers, not for yourself?
