Who didn't race around on a Big Wheel at one point or another during their childhood? Kids these days won't know how much fun we had in the 70's. It was a simpler time.

Take a look at this ad for Marx's Big Wheel. It shows a bunch of kids peddling their brains out, racing up and down the street, and of course, ripping the brake to slide to a stop.

But what's missing? That's right, there are no knee pads, helmets, elbow pads or parental guidance. It's amazing we all survived these things.
