What is the first car on the train?

No, it wasn't on the train. First it was on our feet. The second one was on the boat. The third one was on the horse carriage. Then, the fourth one was on the train, and now it's the cars. We still use boats, trains, cars ect. for transportation, but the best way to use transportation is on our feet. Do you know why, so that we can get the quality exercise we need for our sixty minutes and we can see around our neighborhood. But, if its really far a walk you can use your feet.
