I now fully realize the Hammock Advantage. I normally tent-camp, but I tried a tarp for this 3-day trip in the Missouri Ozarks. I didn't bring my hammock due to consideration for my fellow backpacker, since he doesn't have a shelter and my tarp fits two. I learned 2 things: 1. Tarp camping is every bit as good as tent camping, not to mention lighter. 2. Tarp camping is 100x less comfortable than hammocking. The ground is hard and unforgiving; I wished for my hammock the whole trip. When I did sleep, I woke up with aches and pains. And I'm only 22!
Next time I think I'll trade kindness for comfort.
Thanks to all you people on HF who have shown me the way.
