'T-Rex Stampede' through streets of Nashville

NASHVILLE, Tenn. - They say T-Rex dinosaurs weren't very fast, but you wouldn't know it by watching dozens of them run through the streets of downtown Nashville.

Runners donned their T-Rex costumes and running shoes for the second year of the "T-Rex Stampede." People lined up and ran, crossing a pedestrian bridge and even traffic, turning a lot of heads along the way. 

An organizer says it started out as a joke on social media, but interest quickly grew until it became an actual race.
