I saw how the space elevator in Red Mars turned out though . Amazing if it works , disaster if it comes down . <| sep |> Late , but maybe someone will find this creepy . Backpacking with the husband down a very steep canyon . At the trailhead , the camp caretaker told us search and rescue might be right behind because a man that had gone down the trail the night before hadn ' t been seen since . Told us to look out for circling birds and wildlife that might be attracted to a potential body . Anyhoo , get past the first mile or so , and there is a post box with pencils and paper for people to write their names as they go down the trail . We checked the paper and the last thing written , trailing off the page was Do not go in , it ' s a trap ! 6262015 the day beforeSuper creepy at the time , and under those circumstances , but someone was obviously having fun
