I plan on leaving a note on my front door to call the police. The only drawback is that someone may notice in time to "save" me.
I live far away from friends and family, so I'm not particularly concerned about who finds me.
The one true concern I have is my 2 cats, so it would be important for me to be found within an a day or so so that they can be returned to my mother's home. I plan on leaving sufficient funds so that they can be flown back, but honestly, I had better ensure that is firmed up as I've heard animals are often returned to animal control if there isn't anyone there to claim them.
Sorry for hijacking your thread, OP. My only concern RE the idea above is concerns that I would be implicating someone else depending on your local laws, but maybe this has been done to success here before.
