Here's an interesting application for GPS asset tracking that thankfully doesn't apply to us here in south-central Texas, at least not very often. In this article GPS World reports about the system that many major cities up north are using to track their snow plows, and then provide mapping information to residents showing which streets have been recently plowed.
So glad this isn't an issue where we live! Even if we had the snow plow map at our disposal, we'd probably call it a "snow day" and track the plows from the comfort of our own homes. Just one of the many perks of living in Texas.
