I would only do it from a live boat on a day with very low exchange at slack, that should be a clear indication of how dangerous this site can be!! I love diving but safety should ALWAYS come first...
well, i have decided that i won't be diving deception pass on may 6/7. even with a one to two foot exchange the weakest current prediction i can find is still 3.5 knots. that is a bit stiff when coupled with the unpredictable nature of the flow in that area. i don't care to take on a merit dive just to say i did. just not worth the risk to say, "yeah, well, i dove deception".
