Okay, so from what I can see the travel guidelines are just that, guidelines, so I do wonder if they would even be enforceable in law.
It also says if you need to travel for a suitable recreation/outdoor area you can, so technically if you’re inland and your recreation is coastal, you’re not actually breaking the rules by travelling to the coast. In theory?
Im by the coast so okay, don’t need to go particularly far, but this lockdown has more holes in it than a landing net.
I’ll observe for a couple of days to see how keen plod is (I suspect not much) but if I want to go, I’ll go.
I figure worst case, if they stop you, be polite and they’ll just ask you to return home.
