Cremated and spread my ashes in the ocean.
Two reasons why, first I belive that land should be used for better things then holding my remains. Build a family a home, park anything that would bring joy to the living.

Second I don't want there to be a place that my family can go to to morn. I've seen people standing over a grave site, talking to their loved ones, crying etc. I don't want that, if they need to talk to me I'm where ever they are and if they want to cry....I'll be there too. It's only my shell that rests in the ground, not me. I don't want them to morn over an empty shell.
