The regulations don’t apply to private spaces and only when in sight of the protected locality in the centre of the red circles.
And there are other regulations, so many other regulations…
But hey, I can at least legally consume in the privacy of my own home now, so I got that going for me, which is nice.
Yeah I worded that badly. It’s allowed if you are in the line of sight of a protected locality but more than 100m away. The law specifically states line of sight means less than 100m.
