"Right, so here is how it will happen. Each member can submit one picture of their car, this will start around the end of October when we have hopefully had some decent weather. All members then get to vote which 12 pictures are the best. These are submitted to the printer who makes a great job of turning them into a calendar. I will put some sort of convoy picture on the front."
Or you can put forward a picture of someone elses car with their permission. One submit per member though.
