I spend a lot of time in a CMD window. I mean a lot of time. Often I'd like to open a web page, but opening up Internet Explorer and navigating my way to the page in question is such a chore. I'm lazy. I don't like mouse-clicks. Enter the quicky batch file.
traffic.cmd - This checks my local traffic conditions (thanks to the excellent folks at the WSDOT)
weather.cmd - This tells me the current conditions in my area
You get the idea...
