I just up-voted you but your vote total is not changed, so I guess my Steam Power is low at this point.
This is fascinating stuff. I once heard a story about a person who took care of elephants for a long time and when he died elephants came, some from far away, circled his house several times and in marching formation, and then left.
I have no idea whether this is just a fairy tale; but I would love to know whether you consider this kind of behaviour to be something to expect with elephants, even if the details of the story may not be correct.
Cheers!
