At the Montgomery County Fair Me and my girlfriend rode a gravity driven dark ride that had a chain lift and a dip right after that. The rest of the ride was wild mouse turns and a guy who stopped the cars using his shoes as a break. The cars had four caster wheels on the bottom of them. The track was extremly narrow, was metal and had two rails. The ride was called Mouse Trap dark ride. Who made this ride, and how rare are these rides?
