Warning: Avoid the plank road. A public warning was issued yesterday by the El Centro branch of the auto club of southern California that travel to Yuma via the plank road is dangerous. . . Parties attempting to travel suffer from thirst and hunger and are sometimes in danger of death as there is little chance of succor arriving unless a call for aid reaches Holtville or Yuma. –Imperial Valley Press, April 29, 1919.
