First, thanks to all for the tips on Tunnels. We dove with Fathom Five's co-owner Jeanette and had a great time. Given the complexity of the site, and Jeanette's great skills and personality, I felt like we got our money's worth. We'll be diving with her again on Sunday.
Speaking of which, thanks to Dave for the pictures. I'm practically wiping drool off my keyboard right now. We can't wait to get out there, and I have a feeling I'm going to want to come back sooner than my wallet does.
Last but not least, aascubagirl: I recognized the background of Dave's shot as the one from your avatar so I clicked on it. When your picture/profile popped up, you looked familiar. "Wait a minute..." I thought, "I think I walked right past her!". Were you at tunnels today? If so, I'm 99% certain you were walking towards the water as we got out after one of our dives. Sorry I didn't stop to say hi. We'll have to make a point of diving with you guys on a future trip. We're from Oahu so it's not that tough for us to swing by.
Thanks again guys, I might post a short Tunnels/Niihau trip report if I get a chance. Mahalo!
