I keep somewhere between 5-15 hives a year on the coast in the Pacific Northwest. In an average year a few of my hives swarm or die and produce nothing, a few produce a few gallons of honey, and a few produce 10 gallons or more. My three kids eat honey every day with their breakfast, my wife is constantly using it for baking and homemade granola, we make 5-10 gallons of mead every year, I give a quart to everybody I know for Christmas, and in some years I can also make a couple thousand bucks selling the leftovers through a local shop. It's my only hobby that pays for itself plus more. Everyone should have a few backyard beehives.
