I think the longest I've been up is around 36 hours. I was on the pep band at Washington State University, and the night before the PAC 10 Women's Basketball Tournament, we decided to not sleep and stay up all night playing Wii and Xbox on a projector with a huge screen. The following day we had to play music all over San Jose, CA. Staying awake while playing was a bit difficult.
What part of San Jose did you play at?
