Farm owner Alan Sadler told 13WHAM News reporters that while he is grateful his family is safe, he will continue to feel the loss of the cows well for a long time.

“These were yearlings,” Sadler told 13WHAM News in a report available here. “So, next year's probably the main thing that's going to hurt us.”
