How Long Are Your RPG Sessions?

I'm going to continue posting polls each Monday for a few more weeks, because I'm very curious about how the other half lives, so to speak. I know my own experiences gaming, especially over the last decade or so, are quite unusual, so gathering this data gives me a bit more insight into what my fellow roleplayers are doing (at least those who regularly read this blog). As always, please feel free to use the comments to clarify or expand upon your vote.

I've kept both of the previous polls open for now, so, if you haven't yet voted in those, please consider doing so. The more votes they receive, the better the picture I have. My intention is, sometime after all the polls are closed, to do a brief analysis of the results.
