No, any cheap GPS is a thousand times more accurate than stupid
triangulation from sellphone towers, a patchwork system because GPS
doesn't work inside buildings where it can't see the satellites 16,800
miles away.

If you REALLY care for your son's safety, Spot will give you a spot
device free just for subscribing to their service. It makes accurate
fixes to the spot web server you can keep running, if you like, within
about 3', every 30 minutes, 24/7. No access to spotty-in-the-woods and
no-service-in-the-backcountry-mountains sellphone service is necessary.
Spot transmits to INMARSAT low earth orbit satellites passing over its
position. If you son's group gets into trouble, he simply presses a
button on the little Spot box to call for help, directly through the
satellites to Spot, from anywhere on the planet.

I THINK Spot still will give you a Spot device for free. They do
specials every once in a while, but that's not an issue for you now at
this late date. Call them and ask them if the free Spot device special
is still going on. They'll deal in this depression.

Is your son worth $50/year for unlimited service? $7.95/yr is the
Search and Rescue addon and well worth it, if he is...(c;]

I have friends who own a nice pleasure trawler. We track them on Spot
whenever they are at sea by simply logging on to their Spot webpage:

Poor babies are stuck in Marsh Harbor, a Bahamian resort, on their nice
trawler yacht. Don't you feel sorry for them?...hee hee. He's
converting rum into urine by this time a day....a chemical engineer.

AH, HERE IT IS:

Sign up for two years of unlimited Spot service for $99 and the whole
cost of the Spot satellite system for your pocket is REBATED, making it
free. $99 is a bargain for the safety of your son and his party.....

Please don't depend on intermittent sellphone service in some big forest
for your son's ability to call for help. Get Spot free and buy the
Search and Rescue service for a pittance. You'll know EXACTLY, within
about 3 ft, of where he is, every time Spot position reports, 24 hours a
day, 7 days a week. Just tell him to turn it on while they're on the
move. Go see all the neat stuff it does. It really works
fantastic...anywhere on the planet!

If a man goes way out into the woods all alone and says something,
is it still wrong, even though no woman hears him?
