Meet at El Porto at the north end of the beach near lifeguard tower 45. Email me through meetup.com if interested.
--Edit: This meetup was suggested by Ron and more than 3 people signed up. It will not be a good beginner meetup, maybe too big/steep for the foamies/funboards, for that you might want to go to sunset. It will probably be a good shortboard day, maybe a bit of a workout, and crowded, but there will be lots of waves to go around. I'll probably get in the water before 8 but will wear a watch and come out to meet people at tower 45 around 8:30.
As noted in a comment, I'm planning on checking out this event at Shaper Supply Co in Mar Vista after the surf: http://shapersupplyco.createsend1.com/t/ViewEmail/j/A81178D2B7393EEE/. It's a cool shop where you can build a professional surfboard repair kit, rent shaping bays with equipment, and buy blanks. They'll have bbq, live music, live shaping, and screen printing.
