I have a couple questions for backyard bee-keepers. This is something I'm thinking about doing bees next year. 1. Do you use a Top Bar or Langstroth hive? 2. What strain of bees do you raise? 3. Do you ever notice problems with mowing the yard and getting stung? 4. Where do you buy your bees from? 5. What all care do they need? 6. PICS PICS PICS of your setup and bees. Thanks all!
