My highschool bus was wild. And I lived in a somewhat rural area. The tough kids sat in the back and would roll joints. No one would dare tell on them. The smell of pot was obvious, but the bus driver did nothing. The driver was a young guy. Once someone brought a beach ball on the bus and started hitting it around. Everyone joined in, even the bus driver. Then we got a tough older lady who would pull over to the side of the road and stop and yell if someone so much as stuck a pinky finger out a window. :)
