Braunbehrens once bubbled...
It was one of those dives that just got worse and worse. In the end I had a small deco obligation (this was WAY before I had learned anything about tech diving) and realized that I wasn't sure if my rig was balanced. I went back to the bottom, grabbed a large rock, and held on to it for the ascent and the deco (only a few minutes, really). After I was done, at 10 fsw, I let go the rock because I just wanted to know for sure...turns out I would have been fine.
Still, not something I would care to repeat.
