The Manteca Unified School Farm will again play host to 4,000 third graders from Tracy, Ripon, Escalon, and Manteca when the fall AgVenture field trip will be held Thursday, Nov. 7, from 9 a.m. to 1 p.m. The students from the four school districts will be touring the school farm to learn food gets to their dining table from the farm. The experience also allows them to gain understanding and knowledge of the food grown in their own back yard.
