. . .Although it does nicely illustrate my point about a KISS pocket kit built around shelter for people who aren't as heavily trained.
My KISS kit is centered on navigation as most cases (just like this one) start with getting lost/turned around and "where the hell are we" sets in. A compass and map (assuming you know how to use that lost art), or a mapping GPS, or a compass, map and any GPS.
A non-mapping Garmin Geko can hold a whole bunch of waypoints and the first one you set before walking should be where your car is parked. Then mark points on the trail or just leave it on and it will mark your path. Getting lost is very easy, but not getting lost isn't that difficult.
My walking kit (Camelbak Rim Runner) has all I need to make an expedient shelter and boil water. Tea, chicken soup -- all the comforts of home. . .okay, not all, but enough for an unexpected overnight.
As for my "confession", I don't have a PLB yet, looking seriously at the SPoT, but will probably wait for Doug's final assessment and maybe v2.0.
