hey I'm hiking the eagle rock loop this sunday, and I'm starting to weigh all my gear. My sleeping bag is 4 lbs, and its starting to get pretty hot outside. I've never slept in a hammock, but I would think I'd be warm enough in a tent with just a blanket. If I bring a ccf for bottom insulation and a blanket, should I be warm enough in 50 (that's the low) degree weather?
