LIGONIER, Pennsylvania — All that remained of Ruthie’s Diner on Wednesday morning was charred, ice-encased rubble — the aftermath of firefighters’ desperate efforts to extinguish the blaze that ultimately consumed the modest eatery, which for more than 70 years had served locals and the travelers, anglers, and hunters heading east along the Lincoln Highway.

Several locals pulled into the parking lot and simply stared, at a loss for words as they watched a community mainstay reduced to charred ruins, thin smoke still rising from the ashes.
