ya mon we were just at swept away and brought a large variety of school supplies for the school they help sponsor, mt. aries pre school, shelly simpson arranged for us to visit the school and we also purchased the morning snack for the children, which was a juice box and cookies, the cost to us was about $ 5o but well worth it to see the smiles on the childrens faces
