Been a long time but I used to camp a lot for boy scouts. Sometimes it was a big setup but sometimes it was space blanket in the forest shit.

One time I camped on top of a mountain 8000 feet up, with a 31 degree night that we didn't expect, and I had a shitty sleeping bag and I was so fucking cold. Half of us had normal shitty sleeping bags and half had either a packable cot or a head to toe sleeping bag

I also did civil air patrol (yyyeah) for a while and we slept outside on a huge hill in camo with no tents hiding from people trying to find us, didn't get found until morning
