Head of the Hooch Regatta is one of the world's largest rowing events, with more than 2,200 boats set to compete across 91 events on the Tennessee River in Chattanooga. The race is held at Ross's Landing, a riverside park in the heart of downtown Chattanooga, so you can settle in on the water's edge and watch the action unfold. It's a lively, scenic morning out with boats cutting across the river and plenty of Scenic City spirit in the air.
