I don't do conditional gifts - I'd never presuppose where to send them, or to ever require my ashes be taken anywhere (wouldn't be cremated, be composted anyways after usable organ harvesting was done) beyond standard disposal.

As far as I'm concerned (and after I'm dead there will be no capability for concern anyways) they can do what they like, or not, with any money I've left them.

In a casket just above the casket with my late wife in it.

I've thought about this subject and what I concluded was that whatever brings them the greatest peace is fine with me. As some here have pointed out, I won't be around or in need of my body (especially if it's been cremated) when I am dead. If they want something to remember me by, they can grow a plant. I don't care what kind - a flower, vegatables, a tree, whatever. Plants are something that have brought me a lot of pleasure and enjoyment, so it seems appropriate they could be something to remember me by.

The river Ganges is the traditional and perennial favorite, so I hear.

I wouldn't, as I would be imposing my desires on them. They have their own lives and things they like to do.

What would happen to my ashes would be up to my family I left behind.
