Other vehicles included the horse drawn fire engine. Though not a large capacity ride, it appears to be fun to imagine yourself as a firefighter in the 1910s.
Another way to ride up and down Main Street was to ride these Horseless Carriages. Talk about low capacity, but they were a lot of fun to ride. As can be seen in the background of this photo, the motion really adds to the atmosphere of Main Street.
Final image is of everyone's favorite (well at least one of my favorite) vehicles on Main Street, the Carnation Milk Truck. Usually parked on a side street, it enhanced Main Street. Walt loved to fire this truck up and run it on Main Street.
