A local businessman and his two brothers are hitting the road for a nearly 4,000-mile journey across the country. On bicycle. And for Bobby Jenkins, it's personal.
While all three are riding for charity to fundraise for causes they believe in, Jenkins is riding to honor the life of his late grandchild who suddenly and mysteriously died three years ago.
For months, Jenkins has left work, pulled on his biking gear and put mile after mile on the road.
He's got the lightweight bike. Comfort matters when you're on the road for a long, long time. He was gearing up for the ride of his life.

Turns out he's right. His wife and daughter may give him a hard time, but they agree.
That's because Jenkins is riding this journey for a purpose very dear to their entire family.

You may be familiar with SIDS -- Sudden Infant Death Syndrome -- but SUDC is completely different. It's diagnosed in children ages 1 to 17. SUDC does not explain what happened -- it's more of classification of any unexplained death that researchers are trying to determine.
"We've got to find answers, and we've got a little angel on our shoulder helping us along," Jan said.
With his family at home supporting him, and the memory of his grandson pushing him through every mile,
To raise funds and awareness and to make sure no one else ever loses their Moss.
