Coast to Coast AM is THE iconic all night talk show. I listen for the cryptozoology and space theories, but it's a dim sum of outside of the box topics. Connie Willis is a frequent guest host. She's a veteran broadcaster and has a wonderfully friendly and engaging style.She has also launched her own YouTube channel series, Blue Rock Talk. Again, it's lots of serious investigation into the unknown (but she makes it fun) and you get All Connie All The Time.
Check it out, throw a 'like' and she'd love for you to subscribe. She's the real deal. Some episodes are guest researchers in their respective topics, some episodes are just her talking to you (and you'd swear you were sitting right there with her),
