Okay, let's try this shelter thing they offer here. I found one using the app.
While having "dinner" I figured mosquitos and other insects might annoy me at an unbearable level so I set up the bivy tent and put it in the shelter because it has a mosquito net and will keep me warmer than just the summer sleeping bag. I couldn't fixate the tent to the ground but fixated the rear end with an expander. 🤷♀️
