Graduating class has five sets of twins & three sets of triplets (2016)

[@lealoo6287]

My twins were born in Phillipsburg, Ks, in 1982. That was the year five sets of twins started kindergarten. I discovered that our county had the highest rate of twins, per capita, in the whole nation! Locals attributed this to the Petroleum plant and the Natural Gas production plant. Other's claimed it was the water, lol. In my case, it's genetic. My mother's family has twins going back generations.
