The lonely, quiet halls of school during the summer reverted to busy thoroughfares Monday, as thousands of Davis School District students returned, their voices filling those hallways with sounds of anticipation, excitement and nerves."School is so much more fun when the kids are here," said Whitesides Principal Diane Cahoon, who was surprised to see several kids arrive at the Layton elementary school at 7:30 a.m., more than an hour before classroom doors opened."We encouraged them to go back home, but they were so excited, they wanted to wait. The first day of school is my favorite day of the year, with all of the excitement and nervousness," Cahoon said. "I also love seeing all of the parents come and get their kids settled, and the feeling that everyone wants to be happy and safe."
