Being the day after Christmas, I expect a light turnout. I think Sister will be fine for a small number of people. I'm bringing Marcia Edgar, a graphic designer who has worked on Rails projects in the past. We'll be discussing the Cedro Peak Ultra web site.
I've shifted the time an hour later so people can eat before showing up (Sister has no food). I also figure staying out an hour later won't be a big deal for whoever shows up, since people tend to slack off the days after Christmas.
