Last October, I went camping with Cub Scouts. My two sons slept in the tent, but I wanted to hang. Unfortunately, we were in the middle of a field and the only trees were 40' or so apart.

So I pulled out 6 staves (old broom handles) and lashed two tripods together. I knew that I'd need to pull the suspension lines tight since my ends would be only about 5' off the ground, and I didn't want to end with my behind on the ground. I also knew that I'd need to back up my stakes with more stakes, in a similar fashion as you'd anchor a "monkey bridge."

I'm ashamed to say that I didn't get a photo of my rig, but I did make a diagram:



I also posted more details on my blog: http://digrat.blogspot.com/2008/10/h...ingenuity.html
