Years and years ago, when friends and I would be discussing this topic, I'd tell them to make sure they didn't let anyone apply make-up to me or put a dress on me before sticking me in the box. I have changed since them. I want any of my parts that are useable to be removed and utilized to help others. I have organ donor checked on my driver's license. Also, I share the same sentiments along with what atomiczombie posted - my choice is cremation. I would not enjoy being pulled out of "peaceful dead" to have to go CUJO on some freak who was handling the parts in ... let's just call it ... a disrespectful manner.
And p-le-a-s-e don't anyone get emotional over the bag of ashes and be carrying that around. I love the woods. A friend can toss the bag behind her truck seat and at her convenience, trot over into some nice woods, dump it there with no fanfare and be done with it.
