Yes listened to them both.
Started listening to Lou Gentile 2003. Kevin Smith was also on that same network as Lou back in 2003 but I never gave him a listen then. Finally heard Kevin in 2007. I have all his shows from 2008 onward.
Kevin was my favorite host because I personally thought he asked poignant questions and he was very intelligent. What a f'n loss it was to lose him in 2013.
Kind of ironic that you mention Lou Gentile as I had just found 2 shows from 2003 last night that I had burnt off on a CD. I have more of his shows burnt off but can't find it at this time.
Only recommendation to something similar is Don Ecker. He's been around for a long time and you probably already know of him.
He's another ex-cop, like Kevin Smith, was who got stuck into all these paranormal topics.
