That spot at Boulmer, it was a couple of grumpy local residents who didn't like camper vans parking up at any time, never mind overnight. They badgered the council to get signs erected. Real shame as it was a really good spot for a stopover. There is a nice little public loo there open 24 hours looked after by a local resident who, as far as I'm aware, didn't mind the camper vans either. The beach and immediate sea is used by people flying kites, using jet skis and small boats, general beach-type pastimes etc.
The top sign is about not digging for lugworms and has nothing to do with using the car park.
There's a good pub there, we used to have a meal if we stayed overnight, the landlords were fine about the mohos in that carpark overlooking the sea as they got good extra business as a result and knew it. Boulmer is a tiny two-bit hamlet. In the winter months you don't get much passing trade. The income they used to get from the local RAF base vanished overnight when it shut down just a few years ago. So the ban on moho parking they were not happy about one bit.
I suspect that while a lot of 'residents' around those parts (not just Boulmer) may well be actual long time residents, a lot might also be second-homers, as in holiday homes. And believe me, the second homers in certain places in Northumberland are some of the worst kind. A large percentage are from London and the South. I have a friend (a geordie) with a holiday home herself on the Northumberland coast up that neck of the woods and the tales she tells me about her 'ex pat' holiday home owner neighbours would shock you (maybe not?). A lot are stockbrokers etc. Got me spitting feathers, I can tell you, and I don't even live there! They contribute absolutely zero to the local economy, and as to what they do to put spanners in the works the rest of the time for people who actually reside there full time.... need I say more? And they wonder why there's a north-south divide!
So it's not always just down to irresponsible mohos who cause problems for other mohos, it's can also be down to truly selfish nimbys with absolutely no valid reasons to object. Where the mohos could park at Boulmer is well away from blocking their views etc.etc. I could go on, but what's the point? {yawn}....
PS Northumberland is not Spain, channa, the inside story on this particular hamlet we've actually heard first hand from friendly residents and it has nothing to do with mohos leaving crap behind.
