You better get that written up and signed by a lawyer. My Dad always wanted to be cremated and his ashes put in the cattle gaurd at the entry of our ranch (the big hole with a grate over it to keep the cattle in). He said that way the would always know the comings and goings of the farm. He got cremated but my mom burried them. My Brother and I have agreed that when my Mom dies we will dig him up and spread half his ashes in the cattle gaurd. and leave the other half.
I have a Harley that I would like to be painted with my ashes mixed in the paint (with some left over for the eventual wreck). I have never heard of anyone doing this and like the idea of my ashes going 120mph down the highway or possibly doing a wheelie. Now that's living (or dying)!
