Blackpool was honestly quite pleasant in the 70s. The grandparents used to take us there. Donkey rides up the beach which was clean, tram rides, the lights, fish and chips, the pier, the tower, the fun fair, the arcades, the zoo, the Dr who museum, jumpers for goal posts etc etc
I went early 90s to pick a car up and it was a filthy smelly shithole in a state of disrepair.
