DALLAS -- The marquee outside a Dallas Whataburger didn't advertise any big burger deals. Instead, it welcomed their "biggest fans."
Karl and Carol Hoepfner arrived to the last Whataburger on their checklist on Wednesday, completing their mission to visit every Whataburger in America -- that's 728 restaurant chains in 10 states!
There were 722 Whataburger locations when the Hoepfners set out on their journey in 2012. But while on the road, six new locations opened. They made sure to his those, too, bringing their total number if Whataburger stops to 728.
The wayfaring Whataburger fanatics received quite the gift at their final stop in Dallas. Whataburger COO Clifton Rutledge and Hugh Dobson, son of Whataburger founder Harmon Dobson, presented them with a new van wrapped with a giant red ribbon. The Hoepfner's had put more than 20,000 miles on their own van, so the gift was well received.
A pair of magnets lets everyone know exactly who's inside the van: I'm Whataburger's BIGGEST FAN. But you can call me Carol." Karl has his own magnet on the driver's side door.
The couple, both in their 70s, planned the trip after Carol was diagnosed with cancer as a way to take her mind off her chemotherapy treatments.
They couldn't have picked a better date to finish their tour.
The couple penned their names in the Whataburger history books exactly 62 years after the opening of the first Whataburger in Corpus Christi.
They are both retired Air Force Master Sergeants from Rockport, Texas.
