Voted, along with my sister. St. Charles County Precinct 107.
I put two Ron Paul signs up along the walkway leading to the polling station and they're the only candidate signs there. I stuck around for a while to make sure the Romney aholes that have been picking off our signs didn't take them down, but after sitting there for about 30 minutes there's way too much traffic for anyone to try to do that and not be noticed.
My mom, dad, and my other sister will be voting for him later as well.
Edit: The weather is pretty lousy, spouts of heavy downpour and it's cold.
