New Back Judge

[Junker]

Hey everybody,
I recognize some of the names from the basketball and baseball sides. I'm working my first football game tonight (a "soap scrimmage") at a local high school. I'm in the process of studying up on my resposibilities as back judge. I'm working with a good, experienced crew just to get me going. If you have any advice that would make my nervous cramming a little more productive this afternoon, I'd really apprciate it. Thanks.
