I've kept bees for years here in the western U.S. It's not a difficult hobby, but it can be demanding if you aren't careful of the diseases and mites that can infect the hives. One learns how to watch for potential decimation. Additionally, our harsh winters demand that the bees be fed through the winter. This, again, isn't difficult but can be time consuming.
I keep 4 supers and it's not often that the bees produce enough honey to be harvested for other than our own use. You may liive in area that can produce more out of fewer bees, since ours have to travel distance to find th epollen.
You may wish to read about the world wide decimation of bee hives (called Colony Collapse Disorder (CCD)). Our County Extension Agent believes the scientists are getting a handle on it... but serious, nonetheless.
Have rheumatoid arthritis? It's often helped greatly by bee stings. In fact I have an elderly neighbor that comes to the bee yard about once a month and waits for bee stings. He's gotten so he can move the bees to his hands, where the symptoms are the worst. He swears by it...
At any rate, good luck!
