From what I'm reading, it's going to take a lot of money and extra weight to get down to a temperature I can get just laying on the ground.

For now, the Speers Peapod is looking the best, but I'm not ready to spend $389 to get to 20 degrees when I can do that now on the ground with the tent.

Meanwhile, I'll experiment in my yard with space, no space, different combinations of clothes and things to see how low I can get. Right now, the high 40's is all I've tested. If I can get to 40, that would be fine for my summer camping.

The ridgeline didn't work. The space is there anyway with the bag over the hammock, so there is no need for it.
