That's funny, I just made a post about the same thing. Following a bee back to it's hive from the field is called "Bee-lining". I guess the theory is when the bees leave the field, they make a direct path , or a bee-line, back to the hive. There's a trick to doing it and I've never done it before. I was trying to find out how successful people had been by doing this old art.
Congrats on the cool find. $5 a super, not bad! Do you get the frames and stuff too? Or is it just the body?
