I thought about that as there are a lot of them around here but the abdomen looked SO hairy.

There is another possibility, Camponotus chroamoides. Usually chroamoides has a large amount of red on it and easily separated from pennsylvanicus, but in the southern parts of its range especially, chroamoides can sometimes get very dark where they overlap in color.

This one is dark enough that I feel good calling it pennsylvanicus, but the way to differentiate them is the microscopic hairs on the edges of gastric tergites, which almost never show well in photos.
