Los Trompos in Detroit.(River City Company, Esrawe + Cadena, Creos, Downtown Detroit Partnership)

Think of a spinning top.

Make it larger-than-life.

Wrap it in colorful fabric with traditional Mexican designs.

Climb into the top for a ride - or make it spin from the outside.

Eight of these tops, in various shapes and colors - known as Los Trompos - are the heart of this year’s Rock the Riverfront activities at Chattanooga Green Park, starting Friday through April 16th.
