I have seen a lot of Dead and Phish shows in my day. 4+ years sober - Definitely not suggesting anyone go take acid and this is a bit of an odd topic for a recovery website, but the human brain and human condition is quite interesting to me.
Ever head about "The (Greatful Dead) Family" back in the day? Thumbprint? Not sure anyone comes back from that.
