Paul and Patrick (born 17 minutes later), 60, from Pittsburgh, Pa. are political opposites. Paul is right handed and a centrist Trump supporter, while Patrick is left handed and left of center. It was a process to bridge those differences, they said, although their arguments were never personal.

They sing together in the center section of a choir at a predominately African American Baptist church and both served a stint in the Navy.

Tara and her sister Cara, traveled from Michigan for their 8th Twins Days festival. They were nursing their newborns while Cara was described as a bit of a hippie and Tara a "fancy nancy." I've lost track which said this, but "she's kind of the bitchy one" also came into the equation.

Carlie and Rachel Knott, 10, of Somerset, Pa., have attended Twins Days every year since they were born.

The pair donned medals from one of this year's "most identical" competitions at the festival (there is also "least identical" judging).
