We went to Maritime Festival a few years back. There was this bloke having a massive argument with his wife behind one of the pubs down at the quayside near where they've built the new bridge. He started hitting her about the head. Someone must have called the police but this man was absolutely crazy, out of control; when the policeman arrived he laid into him with a wooden bat. It was shocking we didn't know what to do. And then the crocodile ate all the sausages. We had a campervan that year and stayed behind an old (glue?) factory on the quayside. We onlt stayed one night but if you don't mind having no facilities I shouldn't imagine you'll have any problems there (there were a few doing the same as us).
