It's just a few snap shots, don't stress out about it. The great thing is when the cameras come back we get to see a little slice of life from all over, so anything is fine and interesting. Maybe a picture of the car that has been its home for the past few days, maybe the street where you work after the rain. Just carry it with you and I am sure you will get a chance to snap something you like in a short while and send it on its way.
