This might be off topic, but can you really just spread human remains willy-nilly like that? I know people do it, but from what I understand, you're not supposed to. Sure, it may "just be ashes", but it's human remains nonetheless. We cremated my late father in law here in California, and first we wanted to spread his ashes at sea, then we thought we wanted to have them interred, then we thought maybe we'd hold onto them. Every time we changed our minds we had to update our permit for human remains. While I think we can all probably agree that spreading a handful of ashes in the wilderness is not really that big of a deal in the grand scheme of things, legally speaking, would you want to publicize that?
