I am also quite curious to see where in CSUN this will be held. I live 4 minutes away and am there a lot for other things, and I can't seem to pinpoint a part of campus that I have been on that would be a suitable place to have a Vex event for over 1000 students (thinking about the team areas and all). Then again, the campus probably has an area somewhere, I mean if not this event wouldn't have been placed there.
But, a best of luck to the group and teams who are running/helping/planning it. I would like to help out and am sure the rest of the team would as well, so don't hesitate to ask!
