I was going pretty of hard on LA in my earlier posts but it really is a dope city.
It's skyline isn't dense but it's a west coast city and density is really an East Coast attribute.
DTLA has always felt "empty" to me, so I think adding some skyscrapers would help it feel and look more full/busy.
The original trolley tracks are still there I think, just under the street gravel. Imagine a Trolley right near Venice Beach
Biggest mistake the city planners made was getting rid of the original pub. Transportation model. Think of how much that would've helped traffic
