I have fond memories of listening to the emergency scanners at my grandmother's house when I was a kid. When I stumbled on Radio Reference, a site where you can listen to just about any emergency scanner broadcast anywhere in the nation, it brought back memories. It is so simple, just select the state, then the community, and finally choose police, ambulance, or fire department. The site also allows you to tune into Ham radio broadcasts if that's something you enjoy. Radio Reference is free to join and is a fun diversion from the normal sources of entertainment in your life.
