I'm not trying to bash, but are you being sarcastic? I've been to the cave and didn't see anything out of the ordinary. Is there something there I missed?
I guess we have different opinions on what's cool.
To me diving into that beautiful cave with the crystals and stagnites, the fishes, music and the sounds of the water around me was really really nice. I love the wasteland for the endless action and killing, but sometimes it's nice to find those hidden sanctuaries, that are just there to be wonderful to watch.
