Trucks and heavy equipment emblazoned with the distinctive diamond “B” logo parked on the banks of the Tulare Lake Canal late last month weren’t sending a subtle message. The giant JG Boswell Company has little love for Sandridge Partners. Nor for the man who runs it, John Vidovich, nor for his current pipeline project that will move water from various places in Kings County to various other undisclosed locations. Trenching for the pipeline was slated to cut under the Tulare Lake Canal in late January but the canal company, which is controlled by Boswell, made several demands.
