Diving is all about limits. Threads like this help the uninitiated learn where the lines are when it comes to shenanigans. Defacing a cave with graffiti or putting others in danger certainly doesn't fit our definition of shenanigans and no one has suggested that. I do have to admit that suggesting that this is what this thread is about is hurtful. Me? I would love to hear more about past cave shenanigans about the pioneers in this sport. Like our current crop of cave divers, I know they had a sense of humor.
