Verizon's location feature uses a combination of "real" GPS and cell tower
location. It's really a "best of both worlds" thing- GPS accuracy outdoors,
and lesser, but better than nothing, accuracy indoors.

Seems like a cool service, but it's a backpacking trip- they're not visiting
Indiana Jones' Temple of Doom! Whatever happened to the days when an
"emergency camping kit" was a bottle of water purification tablets, a box of
waterproof matches, and a good old-fashioned flare gun ?

Today, it seems amazing that as a race our ancestors managed to crawl out of
the oceans onto the shore without a GPS in one flipper and a cellphone in
the other!
