This sounds like it will be a ton of fun... I had wanted to write about this earlier in the week, however I have been on a roll all week and barely around.
The Santa Monica Pier and beach surrounding it, is holding a big 12 hour FREE FESTIVAL from 7pm until 7am!!! Music, Carnival performers, art installations and I am sure a few reach-arounds that are in no relation to the event!
I will be leaving shortly, having just returned home from work.
Please refer to the links below for futher information!
