I always wanted to try this, but you really have to make sure and do it the right way. in other words, don't hold me accountable if you go and die. here's the idea in a nutshell: choke a single line around a branch using an appropriate knot. SRT up it about 3-5 feet off ground. bring a similar, but smaller piece of rope that you can use to create a false noose around your real rope, just make sure that it can't grab the rope no matter how hard you try. climb back down and put on some loose fitting clothes (big jeans, flannel shirt?) over your harness and maybe a long wig to cover the back of the rope. You might want to throw on a mask and gloves for extra scare factor as people will assume you are a dummy. Now, climb back up running the rope through your baggy clothes and throw that extra safe noose that you made around your neck and hide any excess rope in your loose garb. Might work better with some suspenders and a croll. Anyway, just a suggestion.
