Be responsible and go to my already scheduled and invoiced tech work thing that would maybe be able to be rescheduled, but if so, it would be a real pain for the people paying me; or go to the red to shoot a serious rockstar / personal hero doing an FA?
I'm sure there are alot of people asking themselves the same kind of question these last few days. Hell I'm pulling my son our of school earlier so we can head down. Got have your priorties straight or at least a good excuse.
Tell them that the demands on your time are so great that you can't make the scheduled date, but that you might be able to reschedule. And, by the way, rates are going up a bit. You know, supply and demand.
