1) The website trumpets sharks, sharks, sharks. Are there really so many encounters at PG sites? I love to see them, but my gf is a bit wary (she saw a little 1m white tip resting on the bottom in the caverns of The Grotto, in Saipan, and didn't dig it.
Maybe PG has changed but I only saw a shark once there in about 50 dives or so in 2004/2005.
