All kinds of cool, neat stuff I haven't had time to play with yet.
The radar page, it is pretty good for if you have a crew in an aera and you can determain (via DTN's help) how long the weather (rain-snow-sleet-etc) will stay in the aera.
It has some forcasting.
Lots of other stuff too.
I do not have this service, but it is at friends places, and a supply center I frequent.
For the price they have paid for it over what I can get for free on the internet, I have decided that the info I get from them over the Nextel radios, and off the WWW, it is sufficent enough for me.
Other than the up to the second doplar radar, I didn't see other uses in it for the $90 (they advertize "as little as $3 a day")a month.
