At the Petersen 1
The third floor of the Petersen Automotive Museum is for kids. This mural is just the right size to pretend to drive a Hot Wheels car along, and it is conveniently located near the Hot Wheels check out desk. (Which also happens to be the Pine Wood Derby car check out desk and the marble track check out desk, too.) You can race cars down big tracks and play with trucks on a big rug. You can also sit on a some real vehicles.
