Inside/outside Ha Long Bay

Wow! We were dumped onto a Junk for a sail among the rock outcrops in Ha Long Bay, then into a huge cave on one of the larger islands. Amazing. It was misty and cool but the views were still great. Even the grub on the Junk was decent: despite one item being described as having a "sweat and sour sauce"
One more day at sea tomorrow before Hong Kong.
