Yea, it's a loaded bus, but the main part (30 miles of interstate - Tennessee/NC gorge @ 45mph + 7 miles of one-lane gravel) is for three students. There's two tunnels on the interestate, trucks are supposed to stay in the right lane, so they use the tunnels for passing zones which is some serious white-knuckle driving because the trucks crowd the middle line so they don't whack their tralier on the arched top.
