Shark Cage Diving - Farralon Islands

[CTA]

Hi All -

My wife and I are giving serious thought to trying some cage diving with Great Whites off the Farralon Islands this Fall. I have been researching websites on this, but thought I would get the scoop from anyone here that might know about it. It looks like an intense adventure, and is something I have always wanted to try. Among other questions, is there a best time to go? They look to limit the season to a fairly short number of weeks in the Fall, and my wife and I were thinking in mid-October simply because it was right in the heart of the season, but would be flexible if it was better earlier, or later. Also, a 'hookah' air delivery system is what is used instead of your own tanks and as a diver, I have no knowledge of this either. Any comments are welcome.

Thanks
Chris
