When Florida farm owner Jim FavreJustify Fullau looked out his window July 20, 2009, during a typical summer downpour, he was mortified to see a litter of day-old piglets struggling to stave off the storm's rising waters in Lee County.

"It's amazing, it's awesome," Angel Roman, Favreau's friend, told WZVN. "It's good to see, though. It's good to see good things in life and this is one of them."
