This weekend marks the last chance to see two exhibitions that peer into Stockton history — a showing of century-old photographs and another on the history of Caterpillar — before they are bulldozed into oblivion.
The Haggin Museum is celebrating the 100th anniversary of earth-moving giant Caterpillar with displays that tell the story of its founding as the Stockton Wheel Co. and later, Holt Manufacturing. And it has the photographs of Lora Webb Nichols, a photographer who documented the gritty world of frontier Wyoming and later settled in Stockton.
Both exhibitions are scheduled to end on Sunday…
