If you are looking for just two good reasons to love public schools, then head to the hills. In the Berne-Knox-Westerlo Elementary School, located in what is regionally called “the hill towns” in Albany County, you can meet up with Judy Tambasco and Roz Moser every Wednesday. For the past 20 years, they’ve shown up at the end of the hall in two small nooks to sort books and index cards in order to provide young students with a bag of stories to take home.
