....... To leave something on your pitch to save it for your return if you go out for the day? Currently near Berchtesgaden and not seen it done yet.
I know off siters who put stuff out to keep a nice spot... disgusting, selfish behaviour and very, very occasionally I have moved their junk and parked in the spot...
Or I will park next door and play some relaxing music quite loud.
They didn't pay for the space and so have NO right to reserve it.
