Places were investors meet

A main concept of the book Think and Grow Rich is to converse and mingle with like minded people. After talking to my math teacher about the future and our own life goals I realized we spoke two completely different languages. Then I thought about all the friends I have and the same thing crossed my mind. I can't become an investor if I don't talk to investors. So besides BP where can I go to meet up with and talk to investors? Specifically in the Mesa, AZ area.
