Rich, one wonders where her head is. This is really getting pathetic. Karen, if you want to fight with me, lets go at if off line , rather than you making as ass out of yourself publicly. An even better idea would be for you to go back to the flaming asshole who told you to use quick releases, and who sent you out after me, and ask that person exactly what their problem is with me, and why that person can not deal with it himself and instead sending you out to try. There is no organization out there with the practical experience of the WKPP. You can either learn from that, our believe the boat monkeys and dive instructor savants who have nothing behind their bullshit. Your choice. Keep fighting or wake up, but stop making a fool out of yourself on here - let the bozo who inspired this come out and do it hinmself. We all know approximately where this kind of stupidity originates, and I can just go ahead and focus on them and embarrass a few of these strokes if you think that might help. I love doing it.
