Glad to find some more people talking about this! I read the Andy Pero last summer and was absolutely fascinated by it. As others have said, certain elements make me question its credibility, but so much of it just seems to ring with truth.
I was so fascinated by the story that it actually became an inspiration for a music video that my band made. Check it out here:
YouTube - The Horseshoe Spatulas - Room 108
I've also been very curious as to whether anyone has been able to verify what Andy said about the Howard Stern show in his story.... I mean, if that episode actually happened, and people remember it, it would be a good indication that there really is some truth to the story...
