Four cars collide into each other, as demolition derby drivers try to push each other out of the ring, or make the other vehicle undriveable during the annual "Rumble in the Ring" at the Weyburn Fair on Wednesday. There were several heats of demo derby riders competing for a spot in the final during the annual "Rumble in the Ring", which was held at the Weyburn exhibition grounds. Also featured during the evening were lawn mower races and a monster truck demonstration.
