I used to listen to this show when we would be driving home from philly late friday night. Sometimes they have guest but most of the time people call in and talk about crazy stuff. Mostly people talk about aliens and ghosts. The guy who runs the show (George Noory) does a great job listening to all these callers stories. You hear some stories and you think "Bullshit" but the host makes it seem he believes every single story. A lot of crazy war stories, and just weird events, its a good way to pass the time while driving or just sitting around doing jack.
