Getting the chance to breathe in the ‘fresh’ country air, see an hours-old calf, watch a milking operation and tour a working dairy farm, kids from Snell’s School in Stockton recently made a visit to the John Bartelink Dairy on Van Allen Road. It was the final tour in a recent spring series and Bartelink has hosted the dairy tours for years, bringing in students from Escalon, Stockton and beyond to get a glimpse of a working dairy farm in operation, so the youngsters can see where their milk comes from. A 15-year board member of the California Milk Advisory Board, Bartelink said dairymen must be their own best advocates and he said hosting the tours is one way to get their message out there.
