Mind I said personal favorite, not necessarily best. I worked for this one. Saw these bears from a long way off. Paddled several hundred meters to get in camera range then stalked/observed them for several minutes until they got close enough together to fit both in the frame and did something interesting. Beatiful male and female still in their fluffy winter coats. I think this is the bear version of foreplay. Soon after they wandered off into the shadows together.
