Best Dive of Your Life

Since this community looks completely empty, I thought I would start a discussion and just ask - what has been the best dive of your life?

I've been diving for a few years and haven't made it to some of the places I would love to go to but I would have to say my favorite dive so far was in Cozumel - I got to see a lot of awesome reef formations, barracuda's, I heard dolphins (didn't get to see them) and tons of fish life.

How about you?
