I can't remember who posted it, but the guy that found a deer head in the lake, had his buddy surface to watch and then he went shallow with the head sticking up out of the water in front of some fishermen and then he went back down deer head and all. I would have paid money to have watched that.
As far as helpful, when I was a total newb as opposed to being a relative newb, many folks took the time to ask me questions to help me make a good decision on my first gear purchase. The only things I regret buying are things that I didn't listen the advice on here. Not only did you guys save me tons of $$$, but I have gear that really works for me that has given me a lot of pleasure.
And I guess another thing is when I had a dive I had no business doing and it went really wrong, folks talked me through the incident so I could learn from it. It was reading in the accident forum beforehand that helped to remember lessons learned there that allowed me a narrow escape. That entire forum continues to challenge me to think and reason about how to first avoid problems and second to have the best hope of dealing with the unavoidable.
