After the 19 families receive keys to their Habitat for Humanity townhouses at 4200 Kingston Rd. early next year and the complexity of daily life begins, it'll be okay if their thoughts don't immediately turn to the hundreds of hands that went into the construction of the complex. But every time they open a window or door or hang a picture, they'll come close to hidden evidence of those hands. Out of sight, underneath windowsills, on the wooden bones of doorframes and random wall studs, secret signatures tell a silent story of those who wrestled power tools, hauled lumber, laughed at silly jokes and shrugged off extremes of temperature.
