Calvin and I were talking about the frogs that annoyed us at camp. He wanted to know exactly what kind of frog it was. So together we listened to all of the frog/toad calls on our favorite website Frogs and Toads of North Carolina
We also found another picture he took the second night.
It was definitely a toad, not a frog. We both described the call as that of a "screaming woman".
So we decided the best fit is the Fowler's Toad. The call is almost a perfect match and the picture is similar.
