Think about how long 50 years is. (If you’re approaching an upcoming birthday for that milestone, maybe don’t. Think about cake and good friends instead).

Five decades. Half a century. 436,800 hours. It’s a long time.

It’s also the years of safe driving that UPS Feeder Driver Ron “The Big Dog” Sowder has just racked up. (Feeder trucks are the big semis that you see rolling down the highway. “The Big Dog” is a cool nickname for someone who’s good at what he does).

Before crossing the finish line Wednesday at UPS’s facility in West Carrollton, Ohio, just south of Dayton, Ron was escorted for the last few miles of his milestone trip by Ohio State Troopers. He was then greeted by a blast of confetti and an enthusiastic welcoming committee at the building.

UPS takes their safety seriously, as anyone who has ever set foot in one of its facilities can attest, and an achievement like this means a whole lot to the company. (In fact, UPS invested $175 million in safety training in 2011). On Thursday morning, several special UPS guests from around the country were on hand for a formal celebration at the facility.

A native of Springboro, Ohio, Ron was fresh out of the Navy when he joined UPS in 1960. Since then, he figures he’s driven more than 4 million miles; transported more than 22 million packages, and climbed into a UPS truck more than 12,000 times. Just last year he was featured on the show “American Trucker” on the Speed Channel.

According to Ron, the greatest benefit of being a UPS driver is “The future. I like that this company is always growing – Never stagnant. It’s great to be a part of an organization that is always looking ahead to what comes next.”

So now what’s next? Well, more great service and safe driving from “The Big Dog.”

You can count on that.
