In the only Kansas caucus I have been to, you just show up, write down you candidate on a piece of paper, toss it in a jar, and then leave. They have videos playing of each candidate that you can sit around and watch if you hate yourself. They also had some cookies that you could eat and some coffee that you could pour into a to go cup. I think maybe if you show up at the very start of the thing, people might actually show up to speak and I'm not sure if you can vote before they are finished or not.
