Somewhere in nature, off the beaten track. I'll take a tent and set it up somewhere nice in the middle of nowhere. I'll enjoy a few days taking in the scenery and one evening I'll enjoy my last sunset, go in my tent and CTB. There will be a note on the tent to not enter, but instead call authorities, in case nobody answers when called out to. There'll also be a note explaining that this was a conscious choice, a plan in the making for several years and not an impulsive act as well as details on whom to contact. At least that's the idea
