I know there are a few different fireworks shows along the coast. What are the best spots to be front and center, or where can you see multiple shows from one location?
In South Redondo just south of the pier on the esplanade you can see Redondo Beach, Manhattan Beach and Hermosa Beach fireworks. Dolphin Park is also a great place to have a picnic on the grass and watch them but driving home after isn't easy.

Just head to any rooftop and you'll be covered :) The Santa Monica Pier would be my choice though for a prime fireworks watching beach spot!
