What have I done?

I signed up for the 24 hour play festival. What have I got myself in for? I was thinking something along the lines of crazy fun/focused application of time. My parents fly in the next day! AT the same moment I should be photographing the divine Mr. Richard Thompson! Aw, heck. If all the 48 hour film fest guys can do it, I can do this. I am praying that my writer won't want me around for the overnight writing part...
