I have picked out this for my funeral too!

It is a couple of hours away from Jessie, but who knows where she will be living when I'm gone anyway. I do not like the idea of being put in a coffin at all! I used to think I wanted to be cremated, but I would prefer to be put in the ground. It seems so natural. I even have some of the music I want picked out!
The cost of this seems to vary. I am going to be making out a will, living will, etc., in the next week or so, and will really have to lok into this. I would want to prepay.
I also think it is a waste of money to pay for embalming, fancy coffins, etc. This is, of course, my personal opinion for me.
