The first few days of summer vacation were hard on Billy. He was there, at his appointed post - that being the school crossing - at the right time of morning, but look as he may, he couldn't find any kids.
He couldn't find Martin, either. The perennial crossing guard, with his vest, sign and whistle, was home for the summer. So were the kids. School was out.
Billy, being the official town dog since Sally passed away on Doc's porch, decided on the fourth day of no kids that he might as well do something else.
