...and other times Whales come looking for you:-
2 sea-kayakers set off at 6am into the waters off Monterey Bay, California, USA to go watch Whales. The waters were full of them. By the afternoon they were tired & just sat in the water with lots & lots of other folks doing the same. In particular, some folks from Sanctuary Cruises were filming the scene.
A humpback whale breached almost entirely from the water. And dropped on top of the kayak & kayakers. Those guys can weigh up to 50 tonnes (the whales, not the kayakers).
The kayakers were wearing life-vests & were OK. They had quite a story to tell once back on land.
