When I am at my desk at the radio station scheduling music I like to listen to the police and fire scanner.
I think it's interesting to hear what's going on around Tucson. And, thanks to the technology of the internet, it's online via a page from the Arizona Daily Star's website (www.azstarnet.com).
Here's the link if you have interest in listening too. http://mizar2.azstarnet.com/scanner/
