I came face to face with a black bear on Chesterman beach BC. He saw me but didn't pay too much attention, he was more interested in eating salal berries, anyhow I kept my distance and slowly backed off and he carried on foraging, it was no big deal
I saw several other bears on the previous day but that was from a boat and for some reason humans in boat, that pay no attention to at all, they don't even look. We got within about 5m, they know when to come down to the fore shore at low tide, they turn over huge boulders with the greatest of ease, searching for crabs and the like.
