I have been very much involved in LNT. I am a LNT Trainer earning my certificate several years ago. I have been involved with our local Boy Scout council and we have a Master Educator in our council. We have held 2 Train the trainer sessions and a third one scheduled early next year. I always sleep in my hammock and educate all who are intrigued about it.Some of the questions are about hurting trees and I explain the steps I take to help avoid damage to the bark. It is my preferred choice of camping and I have to say, when I leave a site, I see really no sign of me being there after a little fluffing of the leaves/needles of where I was. I have taught some awareness trainings to troops as well as the three day weekend training. I have to say the program the Boy scouts have put together is top notch. A lot of info covered. It was designed to train the boy who holds the position of LNT Troop Trainer. After some of the trainer weekends, I have gotten calls on hammock info. I guess I have converted a few. In Florida State Parks, hanging anything from trees is banned. It would be good for LNT to do more promotion of hammock camping if some training about properly hanging a hammock was provided.
