Three years ago when I was fifteen, a group of us in high school in Arkansas decided we’d attend a rally in the big city in support of action against global warming. We live in a rural area and our school uses a number of school buses to collect students from a wide area. That means we’re well used to early rising. On the day in question, a Wednesday, we met up real early. Some of the older students had their own cars and someone had managed to borrow a small bus, so we all had some means of travelling.
