I'm going to visit a stake in my town. What can I expect?

Out of curiosity I'm going to visit a stake in my town, I believe that is the correct term. I'm wondering what I can expect to see and hear, and I would like some tips on when to go, what to do, wear, and so on. It may go without saying, but I don't intend on joining, I just like investigating those things I find interesting.

I know the singles scene is a big deal, as a single mid-twenties male I'm interested in seeing that segment of the church if it is posslbe. I've had some mormon friends so I'm not completely in the dark, but I am far from knowledgeable.

Additionally I've found it frustrating to find information about meeting times broken down by groups. Maybe one of you could help me out with that problem. Thanks.
