If she thinks she can get to/from work every day for four months without getting served, ignore it. My money is on "pay it" since people are creatures of habit and IIRC process servers are paid for success, therefore motivated. They need only get your address (which they have), lie in wait and wait for her to head to work some morning. As soon as she's getting into or out if the car, "here you go, you've just been served" and you lose.

Will she REALLY be wary and vigilant every single day and not engage in predictable behavior/travel patterns until December? I tend to doubt it but maybe...

If you think she can honestly duck it for four months then roll the dice. If you have any doubt, just pay it and get on with life.

How can anyone possibly get busted by photo radar anyway? Don't they have to put notification signs like a half mile in advance warning you "hey, there's a photo radar checkpoint up ahead" in AZ?
