@zem Haven't slept in a makeshift tent outside, that's for sure. How were the temperatures?
@rostiger when I arrived the water drips on my kajak started freezing over.
However I did use only a regular winter sleeping bag, one of those who stops being in its comfort zone at +4. I had a spare summer sleeping bag with me to double up, but I did not need that one.

@rostiger I cross checked temperatures at the airport it had -5 C over night.
