If I had kids in a Vermont school I would force the issue by packing contraband in my child’s lunch every day.
By the end of the first week you would be locked up & your kids in Child Protective Services because of your "child endangerment"!
Pretty soon, they will frisk your kids for goodies.
I would do the same. AND I would show up to have lunch with my child as much as possible and bring our lunches from a local fast food place. I’d like to see the school try to take my lunch from me.
If only more parents would stand up to the schools and tell them off....
