Plaza Camino Real, Oceanside
Although it is technically in Carlsbad, take the Highway 78 to the Plaza Camino Real on El Camino exit. Inside at the Macy's Men's Store end of the mall is a unique rube Goldberg-type of clock with moving billiard balls which clank and roll and bounce! The clock is 2 stories tall and always has an audience.
It is very funny and kids from babies to grandpas stand around and watch it mesmerized.
