Everyone has their "secrets". From strategies, hotel deals, favorite machines, favorite hang outs that you would not want too many people to know about so you can keep it to yourself, connections, experiences, etc...the thought is, if everyone knew, the value would be gone, the rates would go up, the deal would disappear, the casino would find out, the machines would be replaced, etc. we all have something to lose probably. I share 99% of what happens in vegas for me. I will admit too that things that were shared best kept secrets did disappear. But I still go on sharing... do you really think sharing information has a negative effect? Someone taught others how to win at bj by counting and there is retribution by the casino. Many people here have voiced that if something were really good, people would not share it. Why?
