Thanksgiving Season Food Conservation and Recycling during WWI

1918: Rochester was doing it share to help support the troops during WWI during the Thanksgiving season.  This included recycling fruit pits and nut shells for their carbon for use in gas masks.  The U.S. Food administration also encouraged citizens to eat less on Thanksgiving to conserve food for the troops.
