Thanks for that link, Nickleanddime. I had read about the scouts doing that with the t-posts, but haden't seen those photos. I wanted to see if I could do the same thing with lighter weight supports. As it turns out, the ski poles that I have are slightly lighter than my trekking poles, and much more rigid! The only real downside that I see is that I'll need to do a bit of engineering/fabrication to make them collapsable. I do believe that it is very doable, though, and an extremely small weight penalty for some cheap tree insurance.
