Police check

I'm at heysham port, waiting to board the ferry to IOM. Decided to take Millie for a walk, found a sign saying don't go any further, so I didn't. When I got back to my car, there was a police car waiting to interview me, they did a complete check, whatever that is. Apparently, this is a nuclear power station, who knew?
I've had a lovely weekend with friends. And some amusing chats/texts with bill. I'm looking forward to some peace and quiet.
