Well Al, I went for the first time last year not knowing what to expect, and had an absolutely amazing time. I'm the same way - pretty introverted for the most part, but I had a great time meeting people and chatting and making friends. Simply put, everyone is open and nice, everyone is out to help everyone else. I tend to be pretty selfish myself, admittedly, but after meeting the people of CC.C, I'd give the shirt off my back if I could.
