I have just been up there to the Whitfield site and there is a height barrier , a new height barrier, that is marked up at 2.99 metres high. So I didn’t go in but went home. I phoned the duty manager about it and was told that it is marked at that height but is Actually 3.7 high. They realised a LOT of motorhome filled up there with food and supplies before shipping so purposely made it much higher than it says on the sign. They have been having loads of trucks going in and leaving undesirable mess behind so had to stop them. Lidl qabit further did the same as they were packed out with foreign truck every night. Beware I am only passing this and not responsible for it actually being lowered later.
