Start with conditions, not a product
A crack that widens in summer and closes up by winter is doing exactly what Piedmont red clay does around Athens -- and because granite bedrock sits at wildly different depths from lot to lot, the same crack pattern can mean two different things on two different properties.

Athens context
An Athens crack shows up in very different housing depending on the neighborhood -- a historic in-town home, a student rental, a mid-century house, or new suburban construction. Rolling red-clay terrain, mature trees, humid weather, and a long history of additions affect all of them, just not equally.
