Do to a number of factors my first hive is sitting about 20 feet (give or take) off my driveway, near were cars are parked. It's great for quickly checking on the bees, taking feed out to them, etc. But I know in Spring they have those 'cleansing' flights, and I'd rather not have the cars covered. About how far should they be from house and cars? Can I move the hive more that 3 ft. at a time, without causing problems (I seem to remember something about putting a tree branch in front of the hive to force reorientation)? Let me know what you think.
