not allowed to spend the night here

we are in this place today, just fine. Has been completely asphalted again, but 8 picnic tables on a nice lawn, on the river. A toilet building with 2 clean and usable toilets. No sign with prohibitions, so we spent the night here fine and for free.

is currently inaccessible due to maintenance work. It seems logical to us that you are not allowed to spend the night here because the campsite is across the road.
