Problems with filming earlier

Our planned time to film was on a weekend when every member was free. Unfortunately, it snowed pretty heavily and disrupted our plans for filming. Because the planned day was also the day that the snow had started to melt, if we had continued to film, then there would be gradually less and less snow as the filming proceeded. This would have lead to a continuous continuity error of the snow level constantly receding. Of course, another issue was that of freeing up times from other subjects and events in order to film. For example, our lead actress had a lot of photography coursework, which she did mainly in her free time, which didn't leave much of a window for filming to be accessed.
