ok, in the spirit of action, I'll throw out a strawman plan:
on Sunday the 23rd, we'll rendezvous somewhere near Long Beach.
A random site I found with google says the tides will be thusly:

So the 1:30pm low tide sounds like a great time to be mucking about in tidepools. Maybe the folks who enjoy such things can meet in the morning and look under rocks for a while, then we can meet any less adventurous folks for a late lunch, go to the Aquarium of the Pacific, and then go out for beer somewhere or something...?
I'm assuming we're more going for "casual" than min-con with talks and panels and stuff, although I'm all for any show-and-tell we can come up with...
whaddaya think?
