Good checklist ... though I'll confess that I've never taken a PLB. I have taken a PBJ before, but sometimes the J soaks through the bread and kind of makes a mess.
That said, I will clarify that you should make sure to take an updated map. A few years ago a group of intrepid travelers attempted a route in Colorado's Lizard Head Wilderness area. After 3 or 4 days in the backcountry ... they ran into a section of trail that was impassable due to snow (this was in July). One of the group members berated the others for not checking the map to see the route was clear of snow.
I'm still not sure why those hikers so foolishly relied on outdated maps without the automatic snowpack updates. So foolish.
Anyway, the group was able to reroute their trip and, although it was touch and go for a bit if all members of the group would survive, they all made it back to the highway for an interesting hitchhike back to their cars ... but that's a story for another day.
The point is:
1. Put PB on both pieces of bread and the J in the middle so your bread doesn't get soggy.
2. Get updated maps.
3. When hitchhiking outside of Telluride .... well ...
