San Diego 4th of July

[Charlie]

Its getting near one year since I have had my boat in San Diego. I love it down there. I am packing up the family and driving 9 hours to get to spend Fourth of July on the boat. I am trying to figure a good place to anchor so that I can see the fire works. Here is a link to lots of info on SD fireworks.

What I am trying to figure out is where is the best place to watch the fireworks and what time do you need to get there to get a good spot. The fireworks take place off of Shelter Island, Harbor Island and Coronado Island. There are also fireworks on the Midway. I was figuring on anchoring some where in the Harbor Island area and then watching the displays and then heading back to my berth in Coronado Cays. I'm not opposed to the idea of spending the night at anchor but figure that most of the good spots are already full.
I guess I should also mention that my idea of a good spot is somewhere where we can see the displays but don't have to listen to someone balsting rap music from there stereo. Also would prefer to not have to deal with really drunk people, but that is hard to avoid on 4th of July.
Please give me some recomendations if youare from the area and/or know of a good spot.
