What about the scattering? Technically you have to be like 12 nautical miles out at sea to scatter (I'm really referring to dropping a biodegradable urn into the sea rather than a literal "scatter"). The reason I was thinking the cliffs was that there might be an unobtrusive spot that is too rough for swimming right there where I could drop the urn into the sea. I'd really be interested in hearing from people who have done this.
