This started out as a great podcast, I learned so much from the very early episodes, it then morphed from a podcast about trees to a podcast about virtue signalling and a healthy dose of white quilt. Unfortunately the politics of the two hosts has over powered the wonder the magic and wonder of trees.
I don’t care that much about plants but these two guys are my reminder of what healthy masculinity sounds and feels like. They are the type that all my friends are dating or married to. It helps me to remember what I am looking for in the dating world to hear the way they talk to each other and their fans. After a date I’ll listen to this and think about if that guy is similar/different to these two. Thanks for being good people Casey and Alex!
I love ~90% of this podcast 100% of the time!
One of my favorite episodes, it’s very comforting to hear a fellow person that doesn’t have a degree but loves plants a ton.
What a fun way to learn about trees!
