What if your travel plans go wrong? What if you break a leg out on the
trail? What will happen to you if nobody knows where to find you?
http://SendingOutAnSOS.com helps you develop a travel plan before you
set out. If you don't make it back by a pre-arranged date, we send an
SOS message containing your travel intentions to your loved ones (or
other contacts). Hopefully they will come to your rescue!

If one HAS "loved ones", what's to prevent doing the
"pre-arranging" with them? (WITHOUT any fee to some outside
agency?)
