I'm going down to Pompey next weekend for the Bupa Great South Run, and I've got to do a few things around the City before the run. What are the 'dodgy' areas of Portsmouth, as in where are the no go areas? I mean every place has them. If anyone could give me the heads up on where not to stray, I'd be grateful. I've got to go over the the lifeboat station right on the other side of Eastney? God knows. Can I walk over there or should I cab/bus it....?
