— -- For one toddler, the whirr of a motor is the sound of heaven.
When 15-month-old Case Dasch sat on his mother Breanna's lap at the Richland County Fair in Illinois earlier this month watching off-road vehicles circle a dirt track, he couldn't contain his excitement.
Breanna Dasch, 23, recorded her son freaking out in excitement in a now-viral Facebook video that's been viewed more than 10 million times.
"We live out in the country so he's very into motors," Breanna explained, adding that even as a baby Case has his own dirt bike.
"But this was his first time [seeing four-wheelers] in person," she said. "He's never been this excited before."
Dasch said "it wouldn't surprise" her if her son grew up to be an actor or a comedian because "he's very animated. He's a character."
"He just makes my day so much better," she said.
