DALLAS – How many corny dogs can Texans (and a few Oklahomans) knock out in three weeks? We’re glad you asked. And we’re glad Big Tex was keeping track. The State Fair of Texas, which concluded its three-week run in Dallas on Sunday, shared a few dizzying numbers on the scope of the annual event, including this one: Over 24 days at the Fair, Fletcher’s sold around 550,000 of its Original Corny Dogs.
