Another good TV show

[PaulB]

Thanks to whoever posted last week about the history of agricultural equipment show - it was interesting. Tomorrow on the History Channel at 8 PM EASTERN time is a special on the timber trade. Interestingly, this is a part of the series called Suicide Missions which usually focuses on things like paratroopers and firefighters.

PaulB, I, too, forgot who posted that and where, but I did enjoy the show. Can you imagine plowing with your tractor without steering and letting a GPS and computer keep your rows straight to within one inch?/w3tcompact/icons/cool.gif

Bird, sure can, and it will add another 2 bucks to the cost of a loaf of bread! But then, its only money, so who cares?

Oh boy, chiming in without seeing the show, but...

In Mt Lassen park, N. Calif, they get oodles of snow. When they plow the roads in the spring, they work by two methods. They had buried a cable in the road, from which they ran a signal down, and picked it up by a reciever if they were directly over it. The wire tended to break when the road expanded and contracted though.

Now, they are testing and proving the GPS methods. Some of the roads are cliffs; they can not see any part of the road to identify where they are at.

The key was the release of military strangle-hold on GPS. Before that, they were on the orders of meters. Now they are sub-meters.

Gosh I spell terrible!
