TRENTON, Mich. (July 23, 2011) Children dance to the U.S. Navy band ensemble, Horizon, during the 61st Roar on the River powerboat races at Elizabeth Park. Horizon is performing throughout the metropolitan Detroit area in celebration of Detroit Navy Week 2011, one of 21 Navy Weeks being held this year across the country. Navy Weeks are intended to showcase the investment Americans have made in their Navy and increase awareness in cities that do not have a significant Navy presence.

These children are barely visible in the corner of one of the other pictures. I like how the reflections in the water form a backdrop for them.
