In a good year, David Hackenberg can make a $100,000 profit from beekeeping, but this past year has been a financial disaster. And it all began one afternoon last November when he checked on some of his hives in Florida. "When I pulled into a bee yard in Florida, there was 400 hives of bees that three weeks before that looked great. And all of a sudden, here we got roughly 400 beehives that are totally empty," he recalls. The bees were gone, and Hackenberg says he doesn’t know where they went. "I mean, I literally got down and crawled around. I mean, seriously, I got down on my hands and knees and crawled around. And there's no dead bees. There are no dead bees anywhere. I mean, you can't find any bees. They flew off someplace," he recalls. The bees, Hackenberg says, never came back. It's something he says he'd never seen before . . .
