Definitely bring your gear! It's totally worth it....and there are lots of local, active divers who would be more than happy to take you out. Pop into the socal subforum and let us know when you'll be down here!
Except for tanks I can drag everything.
Right now 9/30-10/1 is planned. I could do an evening dive on 9/30. But not sure how doable this is as I will be w/o rent-a-car as meeting is right next to the LAX and my hotel is next to LAX.
