Would you go into this cave? First, it has a long tunnel called "the nose dragger" named, because, well, you'll see. And second, at one point I mention that the water is 40 degrees (Fahrenheit). Have you ever put your hand in an ice cooler to grab a drink? Remember how it felt after you left your hand in there for more than a few seconds? Yeah, that's how this was. For perspective, the Arctic Ocean is 28 degrees. And we were submerged in it for approximately 3 hours. Let that soak in for a minute while you check out this clip.
