The problem, here, is defining a city as a place to visit. I've been to LA many times. I always find something to do when I'm not working ... but these are things that happen to be in or near LA. They'd be worth visiting if they were in or near any other city, or no city at all.
I’ve also been to LA, and yes there were a few places, but I think it’s highly overrated as whole. Even California’s nature places aren’t that great, in my opinion. Sure we have a few nice zoos, and many theme parks and beaches if you’re into that, but this state isn’t where I would choose to visit if I lived in a different state or country. Maybe I’m jaded because I live here, but this state is not that great as a whole.
