Grimsby, Cleethorpes and surrounding areas are lovely and home to a lot of people. It's no more a dump that any other town.
Yes it is were the poorer, run down areas but there's re-generation going on.
5 mins by car and you are in the countryside. And judging by the number of Bentleys, and some house prices some are doing ok.
So degrade it all you want, but if you want a nice standard of living and decent house prices, (with garden/driveway) we are doing ok.
