BTW, also being a caver, GPS doesnt work in caves, compass does.

A GPS really doesn't even work that well in the woods. I have 2 and I
always carry them on vacation (Idaho, Alaska, the Dakotas and Wyoming)
but you have to climb a tree to get enough satellites to establish a
fix. My wife was constantly making fun of me waving these in the air
trying to get 3 satellites.
They do work OK in the desert.

Does anyone have any experience with working the GPS from the centre of
a moving vehicle? Does it need to be near glass to receive signals?

Dave, they do need to be near glass if they only have an internal
antenna. There are models that have a connector for an external, and
the external itself costs around $25. There are also units made that
have the external already with it. Especially on trips to places I've
never been, I don't know how I ever got along without a GPS. And
before Mapquest, how did I EVER know where I was?

Heh - good one.

Funny story. When we redid the 911 system and turned it into the
E-911 system, I (and a couple of other radio enthusiasts on the
rebuild committee) fought tooth and nail to get GPS incorporated into
the system. We even worked up a deal with Garmin who would provide
the GPS units at cost for all eleven departments to equip every
vehicle with a unit.

Coulnd't get that one past the local chiefs - they just coulnd't wrap
their collective brains around the concept of exact locations. :)

Eventually though, we won.

They put up reflective house numbers out at the street out here in the
sticks for the benefit of the cops and fire departments. You cannot
get a cab. They simply cannot find the place. Nobody has ever found
this place that hasn't been here before. I like it that way. My
address is not on my checks. My phone is under a fake name. As a
friend once said, ' it doesn't pay to advertise.'

We did that too. As a large geographic area that is almost completely
rural in nature, it was very important as some driveways can be a 1/4
mile long.

We also have an odd situation on my street in that it is actually two
roads that are similar in name - three of the houses on my town's side
have the same number as the houses on the same street in the next town
over.

That is a problem. :)

I'm not too sure about being unfindable. You'd be surprized at what a
competant 911 operator can find out quickly through the phone
companies.

Fake name or no fake name.

The drive is only a hundred feet, but there are trees and a massive
hedge. My place needs at the street numbers, the next door neighbor
doesn't.
