Sorry about your dad.
They allow "Human Composting" here. I'm just gonna get my friend to dig a hole with his backhoe out in the yard and I'll wheel my chair over with a bottle of Whiskey and a handful of Seconal (with a tree to put on top) when it looks like time to check out. 

 idk what I want done when I die.  
Hopefully someone keeps my skull & puts it on a mantle.
