I've listened to the police/emergency scanner online forever and finally decided to buy a real one. $99.99 at Radio Shack and I now have one that doesn't rely on the internet.
Here's how I know I'm with the most awesome person ever: I bought it, picked Anthony up, he sat on the couch while I programmed the thing, he worked on his research project, he went to bed without being upset that I stayed up listening to it. I tried to be a good guy and got out an earbud so I could listen to it without the speaker and it was quiet in my apartment. He still wasn't unhappy that I stayed up. Pure awesome.
