As I'm from a fairly urban area, we not only don't have much strong wind, we don't really have open expanses of greenery. Even if the wind did blow hard enough, it would probably disturb a patch of grass on a sidewalk, or some broken twigs in a bush rather than rush through a huge open field in waves of green. I really never thought I'd see this in real life. I tried to find a gif of the scene I'm talking about, but couldn't find one! If I knew how to make gifs, i'd make one because it's one of my favorite scenes in the movie. This is the closest one I could find:
Your Broad Abroad,
