Im a fan as well, their videos are excellent and they often do trips with other cavers, so you can find other small channels through them if people want more “cave content.”
What trips me out is towards the end of each video where they’ll be like, “Alright, Brad is heading back so I’m going to wrap up too. We’ve been in the cave for 12 hours, probably a good time to head up.” 8+ hours of squeezing through cold, dark passages sounds like actual nightmares I’ve had!
